摘    要:对Ag-6Cu-1Zn-0.5Ni合金楔形试样进行轧制,获得了变形量从33%-80%连续变化的高通量实验样品,并对合金显微组织和性能进行了表征。结果表明,合金塑性变形后,晶粒发生变形,沿形变方向被压扁并拉长,最后全部转变为纤维组织。合金内晶粒从不均匀变形逐渐转变为均匀变形,晶界为滑移带的发射源。随着变形量的增大了,出现了交叉滑移和平行四边形的亚结构。硬度的变化分为4个阶段,呈台阶形式上升,其强化机制为固溶强化和位错强化的共同作用的结果。

关 键 词:金属材料  Ag-6Cu-1Zn-0.5Ni合金  高通量  显微组织  硬度

Abstract:The high throughput experimental samples of Ag-6Cu-1Zn-0.5Ni alloy with the deformation amount was between 33% ~ 80% was prepared by rolling the wedge specimen, then the microstructure and properties of the alloy were characterized. The results show that the grains are deformed, squashed and elongated along the deformation direction after plastic deformation, and finally transformed into fiber structure. The grain gradually changed from uneven deformation to uniform deformation, and the grain boundary was the emission source of the slip bands. The sub-structure of cross-slip and parallelogram appeared as the deformation increases. The change of hardness was divided into four stages and hardness raised in the form of steps, the strengthening mechanism is the result of the combined action of solid solution strengthening and dislocation strengthening.
Keywords:metal materials  Ag-6Cu-1Zn-0  5Ni alloy  high throughput  microstructure  hardness
