【摘要】 通过对不同冷拔变形后的GH3625合金棒材的组织和性能进行分析,归纳与总结了冷拔变形工艺对该合金的组织及性能的影响规律。即经过冷拔变形后合金同一横截面不同部位晶粒度呈现明显差异,合金的抗拉强度和屈服强度与减面率存在近似直线关系,即σ=σ0+100K*A.再者随着减面率的增大,屈服比σ0.2/σb的值逐步增大,并且在总减面率相同的情况下,多次拔制有利于合金塑性的改善。更多还原

【Abstract】 The influence of cold drawing cold drawing on microstructures and properties of GH3625 alloy has been investigated by analyzing GH3625 alloy bar undergoing various cold drawing deformations.The results show that the gain size in different areas exhibits significant difference.Yield strength and tensile strength show approximate linear relationship with reductions,namely,σ=σ0+100K*A.The yield ratio(σ0.2/σb) increases with increasing reductions.Moreover,repeated cold drawing benefits the plasticity of alloy in the case of keeping same reductions.更多还原
