摘　　要：研究了稀土Ce对P9钢显微组织和力学性能的影响。结果表明,稀土Ce加入量小于0.5%时,稀土Ce能起到净化基体和细化晶粒的作用,对P9钢的综合力学性能有一定改善。The effects of rare earth-Ce on steel P9＇s microstructure and mechanical properties were studied. The results show that when the addition amount of rare earth-Ce is less than 0.5%. Ce can purify the matrix and refine the grain size, and improve the comprehensive mechanical properties of steel P9.
