Definitions

the invention relates to a turbine blade for steam or gas turbines as well as compressors, which shovel made of primary material by cutting Machining is created and thermally treated or remunerated.
Turbine blades with one for the respective use in the turbines and Compressors required shape can be made according to the drop forging process by machining from a billet or by forging Raw form with a subsequent chip removal can be created. It will Pre-material from alloys solidified in forms by forging and / or Rolls produced and optionally heat-treated for further processing. It is known to use casting blocks, continuous casting booms or remelting blocks for the To use primary material production.
Turbines for two-phase generators have a number of revolutions of 3000 or 3600 min- 1 , which results in considerable stresses on the rotor blades when the same is high.
the high availability and safety of the Thermal engine turbine blades required the highest possible on the one hand Have material homogeneity and on the other hand a low tendency to creep Have material at operating temperature.
the aim of the invention is To create turbine blades that cut at the flow surfaces are processed and meet the above requirements.
PM powder metallurgy
HIP hot isostatic pressing
the advantages achieved with the invention are essentially that a, after the powder metallurgy (PM) process is essentially free of segregation and a high material homogeneity from it manufactured turbine blade ensures. Even with a high degree of deformation or a large longitudinal stretch of the material, the homogeneity remains, in particular obtained across the cross section, causing no tendency to a There is bending of the free blade ends.
PM powder metallurgy
the primary material after the hot isostatic presses (HIP-en), preferably in a near-final dimension Form, not deformed (as-HIP-ed) is machined can be a special one economic manufacture of the turbine blade can be achieved.
HIP-en preferably in a near-final dimension Form
AS-HIPED "condition, the desired mechanical material properties are not may have, it has been found that such a blade partially even has improved quality features.
the PM raw material is made of an iron-based alloy, which solidifies without ledeburit.
the PM process is especially for Alloys were developed which solidify primary precipitates, for example carbides, and form this process in case of ledeburit freezing Steel cannot be effective in terms of quality, it has surprisingly been found that thus a significant increase in the quality of the blade alloy material is achievable.
a turbine blade for high thermal and mechanical, in particular dynamic loads and a lack of tendency towards end bending in practical use can be created if the PM primary material is made of a martensitic chrome steel with a composition of in% by weight.
Manganese (Mn) to 2.0 Sulfur (S) to 0.49 (Mn / S) MIN 2.0 Tungsten (W) to 2.5 Nickel (Ni) MAX 3.0 Niobium (Nb) to 0.12 Boron (B) up to 0.01 Iron (Fe) rest as well as production-related impurities and accompanying elements.
the synergetic effect of the alloying elements of the PM material is beneficial for turbine blades in several ways.
the machinability of the material is significantly improved; on the other hand, if a certain Mn / S ratio is maintained, the mechanical properties remain unchanged at a high level even with frequent operating cycles.
the PM material is made of a soft martensitic or nickel martensitic steel with a composition of in% by weight.
a chromium content is metallurgical or manufacturing technology, which is at least 14% by weight to nitrogen, which has a beneficial effect on the Exercises material properties to bring in solution.
FIG. 3 A test is shown schematically in FIG. 3.
the sample fixture took place in a holder 3, with a clamping piece 22 of a sample 2 in this was fixed.
a respective one was carried out with different heating speeds Heating sample 2, which is then at temperatures between 300 ° C and 550 ° C were kept. The deviation of the was measured Clamping opposite sample end.
test specimens made from conventional primary material i.e. in blocks solidified steels and subsequent reshaping of the blocks Bends with higher rates of temperature change and increase larger ingot cross sections.
