摘　　要：对铬钼铌合金铸钢的组织与耐磨性进行了探讨。研究表明，铬钼铌合金铸钢经空淬＋低温回火后的组织是以板条马氏体为主的马氏作－贝氏体－奥氏体多相混合组织。其综合力学性能优异，耐磨性是普通Mn13钢的2倍以上。In this paper, the structure and wear resistance of Cr-Mo-Nb alloy cast steel were dis cussed. It was indicated that the structure of Cr-Mo-Nb alloy cast steel after quenching in air and tem pering is M-B-A mixed matrix structure in which martensite is main. The mechanical properties of this cast steel were excellent. It's wear resistance was two times more than common Mn13 cast steel
