采用ＴＥＭ，ＳＥＭ；电子探针和 ＭＤＬ－１０型动载磨料磨损实验机研究 Ｍｇ－Ｃｅ－ＡＩ复合变质团球状共晶体奥－贝钢（简称ＡＢＮＥ钢）复相组织的形成及抗冲击磨料磨损行为结果表明，钢中贝氏体组织由板条铁素体与残余奥氏体组成，团球状共晶体是（Ｆｅ， Ｍｎ）３Ｃ和奥氏体两相伪共晶组织 ＡＢＮＥ钢在中、低冲击工况下耐磨性优于奥－贝钢、奥－贝球铁、团球状碳化物中锰钢，其原因与国球状共晶体可有效地减轻磨料的侵入深度和阻碍微切削作用，以及磨损表面形成大量纳米晶粒和非晶态组织。在亚表层存在形变马氏体与形变贝氏体组织有关
The formation of composite microstructure of the spherical eutectic Mg-Ce-Al alloy (ABNE steel) and the wear resistance of the impact abrasive were investigated by TEM, SEM, electron probe and MDL-10 dynamic abrasive wear tester The behavioral results showed that the bainite in steel consisted of lath ferrite and retained austenite, and the clusters of spherical eutectics were (Fe, Mn) 3C and austenite two-phase pseudo-eutectic microstructure ABNE steels in middle and low The wear resistance under impact condition is better than that of austenite steel, austenitic-ductile iron and spherical spherical carbides. The reason is that spherical co-crystal can effectively reduce the penetration depth of abrasive and hinder the micro-cutting action, and Worn surface to form a large number of nano-crystalline grains and amorphous.
