【 摘 要 】

High-strength manganese aluminium and austenitic steels have the reason of their perfect combination of high mechanical properties and good plasticity for the structural elements. They have the microstructure stability, and goodstrength properties because of the addition of aluminium. The effect of aluminium on high austenitic manganese steel were investigated. The samples wereexamined with several tests such as microstructure, chemical content, and hardness. The effect of aluminiumhad been influenced the formation of the Fe-Al-Mn-C phase and the lower hardness of samples.
