【摘要】 本文论述了不同碳含量碳素钢的组织形态与抗冲击磨粒磨损性能的关系。试验结果表明，钢的正火态抗冲击磨粒磨损性能在含碳量为０．８％时具有最佳值。淬火态的抗冲击磨粒磨损性能与马氏体形态有很大关系。在钢的含碳量为０．４５％时，板条状与片状马氏体的混合组织具有最佳的耐磨性。更多还原

【Abstract】 This paper deals with the relation of the microstructure morphology of carbon steels to its impact abrasion resistance.The experimental results show that as-normalized condition,the0.8%C steel has the highest impact abrasion resistance. The abrasion resistence of as-hardened steel is considerably related to the morphology of martensite and the 0.45%C steel with mixture of lath and lamellar martensite poccesses the optimum impact abrasion resistance.更多还原
