一、前言如何提高在非强烈冲击工况条件下奥氏体锰钢的耐磨数,是当前急待解决的问题。国内外的研究表明有两条途径:其一是采用钼、钒、钛合金化,预先表面硬化处理,沉淀强化处理等手段提高高锰钢的抗磨性能。用这种方法虽然在提高耐磨性方面取得了较明显的效果,但处理工艺较复杂且不够稳定,成本较高,故没有推广应用。第二是从提高奥氏体的加工硬化性能着手,研制新的锰钢材料,使其在较低的冲击负荷下就能迅速形变硬化, I. INTRODUCTION How to improve the wear resistance of austenitic manganese steel under the condition of non-intense impact is the most urgent problem to be solved. Domestic and foreign research shows that there are two ways: First, the use of molybdenum, vanadium, titanium alloying, pre-surface hardening treatment, precipitation hardening and other means to improve the wear resistance of high manganese steel. Although this method to improve the wear resistance achieved significant results, but the handling process is more complex and not stable enough, the higher the cost, it is not to promote the use of. The second is to improve the work hardening properties of austenite, the development of new manganese steel material, so that it can rapidly deform hardening under lower impact load,
