Definitions
- the present disclosure relates to a method for heat treating a multi-material metal turbine blade, as well as the devices which enable the implementation of this method.
- Such a method can for example be used to form metal turbomachine blades.
- Such blades are particularly suitable for applications in turbines and high-pressure compressors.
- each material of the multi-material blades has different properties. This is particularly problematic for the finishing steps of the blade, for example for the heat treatment steps allowing the dissolution of certain crystalline precipitates and the dissolution of the eutectics formed during solidification.
- the temperature ranges of the heat treatments of the different materials making up a multi-material blade can be disjoint.
- the material having the lowest temperature resistance is limiting for the heat treatments of the other materials. Consequently, the microstructure of the materials particularly chosen for their properties over a certain temperature range is degraded. Thus, said desired properties may, in certain cases, not be achieved. The performance of the blade is therefore reduced.
- finishing method designates the end-of-line manufacturing operations applied to a part.
- a heat treatment can be considered as a finishing method.
- the present disclosure relates to a heat treatment method for a multi-material metal blade of a turbomachine, the metal blade comprising a first and a second part each made of different materials, the method comprising: a first heat treatment at a first temperature, the first heat treatment being undergone only by the first part of the metal blade, and a second heat treatment at a second temperature lower than the first temperature, the second heat treatment being undergone by the second part of the metal blade.
- the first and second heat treatments are successive. [0010] This configuration makes it possible to improve the thermal precision of the heat treatment. In particular, this configuration is advantageous for limiting the effects of thermal diffusion within the metal blade.
- the first and second heat treatments are simultaneous.
- This configuration represents a time saving, because the materials of the blade undergo their respective heat treatments simultaneously. The overall time of the heat treatment of the blade is therefore shorter.
- the method comprises a single quench provided after the first and second heat treatments.
- This configuration represents a saving in time, energy and cost, because it makes it possible to avoid an additional heating step which would follow the first heat treatment. Carrying out a single quenching also makes it possible to avoid recrystallization phenomena which can occur when the thermomechanical stresses undergone by the part decrease.
- the second portion of the metal blade is cooled by a fluid.
- the fluid can be a gas or a liquid.
- the present disclosure further relates to a furnace suitable for the heat treatment of a multi-material metal blade of a turbomachine comprising: a hot enclosure configured to be maintained at a first temperature greater than 1250°C and, to receive a first part of the metal blade, a cold enclosure configured to be maintained at a second temperature greater than 1100°C and lower than the first temperature, and to receive a second part of the metal blade, and in which the furnace includes a thermally insulating separation screen separating the hot enclosure from the cold enclosure, and configured to be crossed by the metal blade.
- Such an oven makes it possible to easily implement the method of the present invention.
- such an oven is particularly suitable for carrying out simultaneous heat treatments for metal blades comprising several materials.
- the cold enclosure includes a fluid cooling system configured to cool the second portion of the blade.
- the cold enclosure includes a cooling system and a footprint configured to accommodate and cool the second portion of the blade.
- Figure 1 schematically represents an oven for implementing the method according to a first embodiment.
- Figure 2 schematically represents an oven according to a first variant.
- FIG. 3 Figure 3 schematically represents an oven according to a second variant.
- Figure 4 schematically represents an oven according to a third variant.
- Figure 5 represents the evolution of the temperature perceived by the first and second parts of the metal blade as a function of time, according to a first embodiment of the method of the invention.
- Figure 6 represents the evolution of the temperature perceived by the first and second parts of the metal blade as a function of time, according to a second embodiment of the method of the invention.
- Figure 7 represents the evolution of the temperature perceived by the first and second parts of the metal blade as a function of time, according to a third embodiment of the method of the invention.
- Figure 8 represents the evolution of the temperature perceived by the first and second parts of the metal blade as a function of time, according to a fourth embodiment of the method of the invention.
- the present disclosure concerns the finishing of a metal blade.
- the first part 20 and the second part 22 are made of two different materials.
- the first part 20 may be the commercial alloy CMSX-4 ® while the second part may be the commercial alloy AM1 ®s.
- FIG. 1 shows an oven 100 suitable for implementing the method of the invention.
- the oven 100 comprises a hot enclosure 10 and a cold enclosure 12.
- a separation screen 11 separates the hot enclosure 10 and the cold enclosure 12.
- the hot enclosure 10 and cold enclosure 12 may, for example, be suitable for heating a material by convection or by induction.
- the separation screen 11 is thermally insulating.
- the separation screen 11 can make it possible to maintain a temperature difference between the hot enclosure 10 and the cold enclosure 12 greater than 20° C., for a separation screen 11 having a thickness greater than 1 mm.
- a metal blade comprising a first part 20, a second part 22 and a junction part 21 connecting the first part 20 and the second part 22 is arranged in the furnace 100.
- the first part 20 may correspond to the blade of the blade
- the junction part 21 may correspond to the platform of the blade
- the second part 22 may correspond to the root of the blade.
- the blade is arranged in the furnace 100 so that the first part 20 of the blade is in the hot enclosure 10 and the second part 22 of the blade is in the cold enclosure 12.
- the junction part 21 is then in the same plane as the separation screen 11 of the furnace 100. It should be noted that the reverse configuration is also possible, so that the first part 20 is arranged in the cold enclosure 12 and the second part 22 is arranged in the hot enclosure 10.
- FIG. 2 shows a first variant of the furnace 100, comprising a cooling system 30.
- the cooling system 30 comprises an enclosure under controlled pressure or under vacuum. This enclosure can replace the cold enclosure 12, or simply be included within the cold enclosure 12.
- the cooling enclosure 30 can be cooled using a gas, typically an inert gas such as argon.
- FIG. 3 shows a second variant of the furnace 100, comprising a cooling system 40.
- the cooling system 40 comprises an enclosure configured to receive a liquid in which the second part of the blade 22 can be immersed. This enclosure can be included within the cold enclosure 12.
- the cooling enclosure 40 can comprise a liquid, typically a liquid metal such as liquid aluminum.
- FIG 4 shows a third variant of the oven 100, comprising a cooling system 50.
- the cooling system 50 comprises an imprint 53 (tooling) configured to hold the second part 22.
- the imprint 53 is cooled, and may for example comprise a water or cryogenic gas cooling circuit.
- the footprint 53 can replace the cold enclosure 12 or simply be included within the cold enclosure 12.
- the metal blade is placed in the furnace 100. We are now interested in the control of the furnace 100 which results in the heat treatment of the metal blade.
- Figure 5 represents the evolution of the temperature perceived by the first part 20 and the second part 22 as a function of time, for a heat treatment according to a first embodiment of the method of the invention.
- Each material has a solvus temperature and a burn temperature. To obtain a satisfactory heat treatment for a material, it must be heated above its solvus temperature but below its burn temperature. Indeed, above the burn temperature, the material degrades.
- the first part 20 of the blade is brought to a temperature T between T1 and T1’, while the second part 22 is maintained at a temperature lower than T2, preferably much lower than T2.
- the second part 22 can be maintained at 300°C, or even at room temperature.
- the first part 20 is maintained for a certain time at this temperature T, so that the first part 20 is heat treated.
- the first part 20 can be maintained for at least 10 hours at a temperature greater than 1250°C, preferably greater than 1310°C.
- the first part 20 is maintained at a constant temperature T.
- the heat treatment temperature T can be variable, and for example be a succession of plateaus at a plurality of temperatures.
- the first part 20 is cooled.
- the first part 20 can be cooled by quenching.
- the quenching can for example be carried out according to a method known, using turbined argon.
- the first part can be cooled to a temperature which can be room temperature.
- the first part 20 and the second part 22 are brought to a temperature T’ between T2 and T2’.

- the second part 22 can be maintained for at least 1 hour at a temperature T’ greater than 1100°C, preferably greater than 1290°C.
- the second part 22 is maintained at a constant temperature T’.
- the heat treatment temperature T’ can be variable, and for example be a succession of plateaus at a plurality of different temperatures.
- the first part 20, the joining part 21 and the second part 22 are cooled.
- the first part 20, the joining part 21 and the second part 22 may be cooled by quenching.
- Figure 6 shows the evolution of the temperature perceived by the first part 20 and the second part 22 of the metal blade as a function of time, according to a second embodiment of the method of the invention.
- the second embodiment is identical to the first embodiment with the following exception: during the heat treatment of the second part 22, the first part is maintained at a temperature lower than T2, preferably much lower than T2.
- the first part can be maintained at 300°C, or even at room temperature.
- FIG. 7 shows the evolution of the temperature perceived by the first part 20 and the second part 22 of the metal blade as a function of time, according to a third embodiment of the method of the invention.

During the heat treatment of the second part 22, the first part 20 is also maintained at temperature T'.
- Figure 8 shows the evolution of the temperature perceived by the first part 20 and the second part 22 of the metal blade as a function of time, according to a fourth embodiment of the method of the invention.
- the heat treatment of the first part 20 and the heat treatment of the second part 22 are carried out simultaneously.
- the first part 20 of the blade is brought to a temperature T between T1 and T1’, and the second part 22 is simultaneously brought to a temperature T’ between T2 and T2’.
- the first part 20 and the second part 22 are maintained at temperatures T and T' respectively until they are heat treated.
- the first part 20 and the second part 22 may be maintained at temperatures T and T' respectively for at least 10 hours.
- the first part 20 and the second part 22 are then cooled, for example by quenching.
