摘要
研究了CuCr合金在不同形变和热处理制度下组织中Cr相形貌的变化。结果表明 :当变形量达到 70 %时 ,合金中的Cr粒子产生严重的变形 ,且有开裂现象。在随后 70 0～ 90 0℃保温 2h退火后 ,开裂的Cr粒子发生熔断和球化。
The change of morphology of Cr phase in CuCr alloy under different cold deformation quantity and heat treatment temperature were studied. The results show that when the reduction is to 70 %, Cr particles are deformed heavily, and some of Cr particles are broken. After the following annealing at 700-900 ℃ for 2 h, the broken Cr particles in the microstructure dissolves, and tend to turn into spherical morphology.
