Austenitic manganese steel is used for components which need good wear resistance and impact resistance. The application examples of austenitic manganese steel castings are in the mining industries such as rock crusher and dredge buckets. In the transportation industry, this material is used in railroad track work such as frog. However as-cast austenitic manganese steel is brittle <br /> <br /> <br /> with low toughness due to the presence of carbides. Hence, the as-cast austenitic manganese steel should be solution treated to dissolve the carbides into austenite phase. <br /> <br /> <br /> In this research specimen with varied thickness are produced. The chemical composition in the casting process is in accordance with ASTM A 128 grade A. The solution treatment processes was done using a step heating procedure. Heating temperatures were determined based on Fe-Mn-C phase diagram and by the previous researches. Holding time was determined based on the literature, <br /> <br /> <br /> simulation of heat transfer. The effects of the solution treatment were observed in the microstructure, the grain size, and the hardness of the specimens so that the <br /> <br /> <br /> optimum solution treatment time can be investigated. <br /> <br /> <br /> The objective of this research is to find the suitable heat treatment method in order to produce the desirable material properties. Also to get description about the distribution of carbide in each specimen, and the hardness value as well.
