摘　　要：对喷射成形制备的钢/Al Pb合金复合板材的微观组织,轧制和退火处理后的组织及耐磨性进行了研究。喷射成形钢/Al Pb合金复合材料中的Al Pb合金层经变形量为50%的轧制和320℃×5h的退火处理后,形成致密的组织,Pb相粒子尺寸仅为1～2μm,材料的耐磨性得到提高。Microstructure and wear resistance of spray formed steel/Al-Pb composite strip after spray forming, rolling and annealing were studied. After a rolling of 50% reduction and annealing at 320°C for 5 h the microstructure of the spray formed Al-Pb layer consisted of the Al matrix and the homogeneously distributed and refined Pb particles, 1-2 μm,. The refined Pb particles improve the wear-resistant property of the alloy.
