【摘要】 采用液-固相轧制法可以稳定、连续生产AlSn8Si2.5Pb2Cu0.8Cr0.2覆钢双层轴瓦带。通过金相照片显示其组织与铸造组织相似,但柱状晶(胞状晶)更为细小、发达,组织内Si,Sn等元素分布均匀,在液-固相轧制复合工艺条件范围内,浇注温度对胞状晶组织结构有较大影响,退火则使Sn,Si元素聚集、球化。更多还原

【Abstract】 AlSn8Si2.5 Pb2Cu0.8Cr0.2/steel bimetal strip was produced by liquid-solid rolling bonding. The mi-crostructure photo of aluminum alloy shows that fine, well-developed, compact cell crystals exist in it. In the range of the technical parameters determined byexperiments and mathematical model, the influence of casting temperature on Al alloy structure was studied. The experiment of annealing shows that it has little effect on microstructure of aluminum alloy, but promotes the agglomeration of Sn, Si, Pb.更多还原
