Definitions
- the invention relates to a strain-hardening austenitic manganese steel with an elongation at break of 10 to 80% and to a method for producing the same.
- Cold-hardening austenitic manganese steels have a wide range of applications, whereby both castings and forgings as well as rolled material are used.
- the wide range of applications is particularly given by the high ductility and the good work hardenability.
- the area of application ranges from castings for hard comminution to bulletproof objects.
- the valuable properties of the Hangan high carbon steel lie in the combination of the properties of the work hardenability already mentioned above, and its ductility. Strain hardening always occurs when the manganese steel is mechanically, e.g. B. is claimed by impact or shock.
- the austenite in a surface layer is likely to partially convert into an epsilon martensite.
- Measurements of work hardening show an increase in hardness from 200 HB to up to 550 HB. There is thus an increase in hardness during use when the casting, forging or the like is subjected to mechanical stress. However, since such objects are also subject to an abrasive stress, this surface layer is continuously removed, but a renewed mechanical stress causes the austenite now on the surface to be converted again.
- the alloy located under the surface layer has a high ductility, so that the Hanganhart steels can also withstand high mechanical impact loads without the risk of breakage, even with thinner walls.
- a casting be it a cast or a block casting, is initially manufactured. Due to the properties of this casting, the properties of the objects made from it are then predetermined. If the structure is too coarse in the casting, the ductility of the commodity is then too low. In the case of large castings, as is known per se, this has different grain zones over its cross section. On the outside there is a thin, relatively fine-grained edge zone, to which a zone with coarse stem crystals adjoins, to which the center of the casting with a globulitic structure adjoins. Although the steel is essentially austenitic and work hardenable over the entire cross section, due to the different structure it shows great differences in its mechanical properties, in particular in its ductility.
- the casting temperature be as low as possible, e.g. B. to 1410 o C, to keep, with the increasing supercooling the number of bacteria grows and a finer grain is to be achieved.
- low casting temperatures lead to great difficulties in production. Cold welding thus occurs on the casting, and furthermore the rheological properties of the melt are already such that exact shape fulfillment, especially in edges, is no longer possible.
- the melt solidifies on the pan lining, which leads to pan shells which must then be removed and refurbished.
- the plug can also stick in the spout, as a result of which the casting must be stopped.
- the economic disadvantages which have to be accepted for a non-reproducible grain refinement are so serious that the processes with such a low casting temperature could not prevail.
- Another method of grain refinement consists of a targeted heat treatment, the casting being annealed at a temperature between 500 and 600 ° C. for 8 to 12 hours, which is intended to convert a high proportion of the austenite into pearlite. This is followed by an austenitization annealing at a temperature between 970 and 1110 0 C.
- the two changes in structure are said to produce a finer grain, but at the same time it has the cause that the product becomes extremely brittle during the heat treatment and breaks even without deformation under less mechanical stress.
- Another major disadvantage is that this method requires a large amount of energy.
- Manganese steels usually have a carbon content of 0.7 to 1.7% by weight, with a manganese content of between 5 and 18% by weight being maintained. It is also essential for the properties of a mahogany steel that a ratio of carbon to manganese between 1: 4 and 1:14 is maintained. If the ratio is lower, there is no longer any austenitic steel and it can therefore no longer be work hardened, and at the same time there is less toughness. At a higher ratio, the austenite is too stable, which means that it can no longer be work hardened, so that the desired properties cannot be achieved either.
- a phosphorus content of more than 0.1% by weight causes an extreme drop in toughness, so that, as is known per se for phosphorus, a particularly low value is aimed for.
- ASTM A 128/64 describes four different types of manganese steels, the carbon content varying between 0.7 and 1.45% by weight and the manganese content between 11 and 14.0% by weight.
- the carbon content is changed to vary the work hardenability, which is also to be influenced by the addition of chromium.
- the chromium additives then range between 1.5 and 2.5% by weight.
- Coarse carbide deposits are to be suppressed by adding up to 2.5% molybdenum.
- the addition of up to 4.0% by weight of nickel is said to stabilize the austenite, which prevents the formation of pearlite in thick-walled castings.
- a high manganese steel has already become known which has a manganese content of approximately 5% by weight. With such steels, however, the toughness is already low. However, it has a high wear resistance.
- the present invention has set itself the goal of creating a strain-hardening austenitic manganese high-carbon steel which has an elongation at break of 10 to 80%, which has a structure that is as uniform as possible over the entire cross section and has a particularly fine grain, at the same time without any deterioration in the mechanical properties should occur.
- the mangah hard steel additionally has 0.002 to 0.008% by weight boron, an even smaller grain can be achieved.
- Grain refinement is particularly good when only 0.01 to 0.025% by weight of titanium is provided as the microalloying element.
- the manganese steel has a content of 0.01 to 0.05% by weight of aluminum, the titanium content can be maintained particularly precisely.
- an insert being melted in an electric furnace after which calcareous, slag-forming additives are added to the liquid melt and the desired analysis is set and brought to a tapping temperature of 1450 to 1600 ° C. with an oxygen affinity Element is deoxidized and tapped into the ladle, consists essentially in the fact that the content of the micro-alloying elements titanium, zirconium and vanadium is set in the ladle, and the melt is poured at a temperature between 1420 and 1520 ° C and after the casting has cooled heated to austenitizing temperature from '980 to 1150 ° C and then cooled rapidly.
- microalloying elements By adding the microalloying elements in the ladle, a reproducible content of microalloying elements is achieved. A particularly high level of toughness is achieved by the heat treatment of the casting, heating to an austenitizing temperature of 980 to 1150 ° C. and then rapidly cooling.
- Manganese steel has a lower thermal conductivity than other steels (only one sixth of that of iron), so special attention must be paid to temperature compensation.
- a reliable dissolution of the grain boundary carbides even with larger cross-sections and with lower energy consumption can be achieved at a temperature between 1080 and 1100 ° C during solution annealing, whereupon the temperature is reduced to 980 to 1000 ° C and then balanced and then rapidly cooled.
- a casting with particularly low internal stresses can be achieved by alternately applying coolants of different thermal conductivity after heating to the austenitizing temperature. Water and air are to be used as particularly suitable coolants.
- the casting is removed from the mold at a temperature between 800 and 1000 ° C and then placed in a heat treatment furnace in which the temperature of the casting is equalized, immediately after Austeni tization temperature is heated, so a particularly energy-saving process is given, at the same time a build-up of high stresses in the casting is prevented, whereby pearlitization can be avoided.
- Example 2 The procedure was analogous to Example 1, with titanium in the form of ferrotitanium being added to the ladle.
- the ladle was brought to the mold and it was poured at 1460 ° C. After the casting had cooled, it was heated to 1100 ° C., at which temperature it was kept for four hours, whereupon the temperature of the furnace was lowered to 1000 ° C. After an hour, a temperature equalization in the casting was reached, followed by cooling with alternating immersion in a water bath.
- the Turas thus obtained was free from cracks. With the exception of the marginal zone, which was microcrystalline, the metallographic examination revealed a completely uniform, fine-grained structure.
- the casting had an average titanium content of 0.02% by weight.
- the mechanical properties were almost identical for the specimens removed in the center and at the edge, the tensile strength being 820 and 830 N / mm 2 and the elongation being 40 and 43%, respectively.
- Example 2 For the production of a drop-forged hammer with pin for a rock mill, which had a weight of 180 kg, a block was cast analogously to Example 2. This block was then cut up, and these parts were drop-forged into impact hammers at a forging temperature of 1050 ° C. These impact hammers had a completely fine structure in the area of the pin attachments, which even after the Solution annealing and quenching have been retained. In the case of a hammer which was produced with an alloy according to Example 1, coarse-grained crystals appeared in the area of the pin attachments, which in some cases caused microcracks.
- Example 2 The procedure was analogous to Example 2, with boron also being added to the ladle in addition to titanium. The temperature trip was observed as in Example 2. The casting had an average titanium content of 0.02% by weight and an average boron content of 0.005% by weight. The micrographs of samples taken at analogous locations showed that there were 50 grains per millimeter in the samples containing only titanium, whereas in the samples additionally containing boron there were an average of 60 grains, resulting in a decrease in the average grain diameter of 0.02 mm to 0.017 mm.
- melts were repeated with different titanium contents, the mechanical values given in the table being able to be measured for the various specimens which were removed from the center or the edge zone.
- the tensile strength or elongation at break was determined in accordance with DIN 5 D145 / 1975.
