摘要
研究了包括凝固速率、冷变形和中间热处理对Cu-10Ag合金原位复合材料结构与性能的影响. 观察了铸态组织及其在冷变形和中间热处理后的变化, 测量了材料的极限拉伸强度(UTS)与导电率. 观察到了两阶段应变强化效应, 讨论了影响强度与导电率的因素. 冷却速率在10～103 K·s-1范围内的凝固条件和中间热处理明显影响Cu-10Ag合金原位复合材料的结构与性能.
The influences of solidification conditions, cold deformation and intermediate annealing treatment on the structure and properties of Cu-10Ag alloy in situ composites were studied in the present paper. The changes of structure as cast in cold deformation and intermediate annealing process were observed. The ultimate tensile strength (UTS) and the electrical conductivity were determined. A two-stage strain strengthening effect on the Cu-10Ag alloy in situ filamentary composites was observed. The factors infl...
