摘要
通过真空感应熔炼制备了Co含量为35 wt.%的NiCo合金,本文研究了该合金在不同温度条件下热压缩后组织演变。研究结果表明:合金在中低温压缩后形成晶粒压长且部分晶粒内存在明显剪切带的合金组织;高温条件下形成晶粒细小且存在大量孪晶的合金组织。
A Ni-Co alloy with 35 wt.% Co was prepared by vacuum induction melting. The microstructure evolution of the alloy at different hot deformation temperatures was studied. The results show that, at low or medium temperature, the alloy structure is consisted by elongated grains and there are obvious shear bands in mostly grains;under high temperature conditions, the alloy structure is consisted by fine grains and a considerable volume fraction of twins.
