A. Hadfield) to obtain a high-manganese steel patent. High-manganese steel according to the different uses can be divided into two categories: 2, manganese steel, wear-resistant steel of these 10% to 15%, carbon content is high, typically 0.90% to 1.50%, most of the 1.0 % or more. Its chemical composition (%): C0.90 ~ 1.50Mn10.0 ~ 15.0 Si0.30 ~ 1.0 S ≤ 0.05 P ≤ 0.10 amount up to such high-manganese steel, used to produce excavator shovel teeth, Cone crusher roll facing the wall and broken wall, jaw crusher bifurcated plate, ball mill liners, rail rut fork, hammer, hammer, etc. The composition of the cast structure of high manganese steel is usually caused by austenite, carbides and pearlite formed, sometimes containing a small amount of phosphorus eutectic. Carbon number for a long time, often on the grain boundaries reticular appear. So-cast high-manganese steel is very brittle, can not be used, the need for solution treatment. Commonly used method is the solid solution heat treatment, steel heated to about 1050 ~ 1100 ℃, thermal elimination of cast structure, to be single-phase austenite, and then water quenched to room temperature so that such organizations to maintain. After heat treatment of steel strength, ductility and toughness are significantly improved, so that such heat treatment method is also often referred to as water and tough treatment. Mechanical properties after heat treatment is: σb615 ~ 1275MPa σ 0.2340 ~ 470MPa ζ15% ~ 85% ψ15% ~ 45% aKl96 ~ 294J/cm2 HBl80 ~ 225 high-manganese steel after solution treatment there will be a small amount of undissolved carbides, when The small number of line test, you can still use. Austenitic high-manganese steel under impact loading, the metal surface of the plastic deformation. The result of strain hardening in the deformed layer have significant hardening, the surface hardness increased significantly. Low-impact load, you can reach HB300 ~ 400, high impact loads, you can reach HB500 ~ 800. With the impact load of different surface hardening depth of up to 10 ~ 20mm. High hardness of the hardened layer can resist impact abrasive wear. Strong impact in the high-manganese steel under the conditions of abrasive wear, has excellent anti-wear performance, Guchang for mining, building materials, thermal power and other mechanical equipment, the production of wear-resistant parts. In the low-impact working conditions, little effect due to work hardening, high-manganese steel properties of the materials can not play. China's high-manganese steel grades used and their application range is: ZGMn13-1 (C 1.10% ~ 1.50%) for low-impact pieces, ZGMn13-2 (C1.00% ~ 1.40%) for common parts, ZGMn13- 3 (C0.90% ~ 1.30%) for complex parts, ZGMn13-4 (C0.90% ~ 1.20%) for high-impact pieces. Above four kinds of manganese steel grades were 11.0% to 14.0%. The impact loading of the cold deformation process, due to a significant increase in dislocation density, dislocation of the delivery, dislocation pile-dislocations and solute atoms and the interaction of the steel to be strengthened. This is an important cause of hardening. Another important reason is the high-manganese austenitic low stacking fault energy, deformation prone to stacking faults, and thus the formation of ε martensite and deformation twins have created the conditions. Conventional components of the deformation of high manganese steel hardened layer can often see the high density of dislocations, dislocation pile-and tangles. ε martensite and deformation twins appear difficult to deformation of the steel, especially the latter a greater role. The above factors make high manganese steel to be hardened layer high degree of strengthening, the hardness increased significantly. Easily hardening high manganese steel, making it difficult to process, the vast majority of casting, forging method with a very small amount of processing. Better performance of high manganese steel casting. Low melting point of steel (about 14 () () ℃), liquid steel, solidus temperature interval smaller (about 50 ℃), low thermal conductivity of steel, so the molten steel flow, and easy-casting. Coefficient of linear expansion of high-manganese steel is 1.5 times as pure iron, two times for the carbon steel, so the casting volume shrinkage and linear shrinkage rate of large, prone to stress and cracks. To improve the performance of high-manganese steel alloy of many micro-alloying, carbon manganese adjustment and precipitation strengthening treatment research, and has been applied in production practice. The emergence of metastable austenitic manganese steel can be significantly reduced compared with gao Bureau of carbon steel, manganese steel and to the strain hardening rate of increase, applicable to high-and low-impact load working conditions, which is a high manganese Steel's new development. -------------------------------------------------- - need to withstand high-manganese steel is mainly used for impact, compression, abrasion and other harsh materials, working conditions, wear and tear damage to form the main part of the fracture and deformation. Wear is divided into three types: mutual contact between the surface of metal components and movement of friction and wear; other metal or non-metallic materials against abrasive wear of metal surfaces and flow of gas or liquid contact with the metal caused by erosion. Abrasion wear resistance of steel depends on the material itself, while the wear of steel in different working conditions show different wear resistance, the material itself and working conditions between the two in order to determine their wear resistance. ???? Steel and wear resistant cast austenitic manganese steel in the main, under certain conditions the low alloy steel with appropriate heat treatment has good results, graphite steel is used for lubrication of the working conditions of friction ????? wear especially for the impact of high manganese steel and high-stress abrasive wear crushed abrasive wear condition, commonly used in the manufacture of ball mill liner, hammer hammer crusher, jaw crusher jaw plate, cone crusher rolling acetabular wall, broken walls, excavator bucket teeth, bucket wall, railway turnouts, crawler tractors and tanks board impact, wear resistant castings. High-manganese steel is also used: bullet-proof steel, safe plate and so on. ?? High-manganese steel is a typical anti-wear steel, cast structure of austenite plus carbide. After about 1000 ° C water quenched? Treatment organization into a single austenite or austenite plus a small amount of carbide, but to improve toughness, so called tough water treatment. ???? High-manganese steel of the most important feature is the strong impact, extrusion conditions, the surface hardening rapidly, so that the Department of mind remains austenitic good toughness and ductility, while hard? Layer with good wear resistance. This is less than the other materials. However, the wear resistance of high-manganese steel have enough to form only in the hardening conditions to demonstrate its advantages, other cases are poor.
