通过在奥氏体中锰钢基础上分别或复合加入合金元素Nb、w、Ti、B、N、Cr、Cu,以便在奥氏体中形成适量弥散分布的第二相,从而提高在非强烈冲击工况下的耐磨性。当冲击功为1J时,把合金化的奥氏体中锰钢的耐磨性同Mn13钢及普通中锰钢相比较,得出相对耐磨性的大小。由实验可知多元合金化中锰钢的耐磨性相对Mn13钢的耐磨性提高了68~118%。从微观分析结果,对耐磨性的提高进行了探讨。
By adding the alloying elements Nb, w, Ti, B, N, Cr and Cu separately or in combination on the basis of the manganese steel in the austenite so as to form a proper amount of dispersed and dispersed second phase in the austenite so as to improve the non-intense Abrasion resistance under impact conditions. When the impact work is 1J, the wear resistance of the alloyed austenitic manganese steel is compared with that of the Mn13 steel and the ordinary medium manganese steel to obtain the relative wear resistance. It can be seen from the experiment that the wear resistance of manganese steel in multi-alloying is improved by 68-118% relative to the wear resistance of Mn13 steel. From the microscopic analysis of the results, the improvement of wear resistance was discussed.
