【摘要】 采用等温热压缩试验对一种自行研制的高强度易切削锌基合金进行热变形行为的研究。结果表明:锌合金热压缩变形流变应力随变形温度升高而减小,随变形速率增大而增大;可用包含变形温度、变形速度和变形程度的Zener-Hollomon模型来真实地描述该锌合金高温变形的流变行为。更多还原

【Abstract】 The hot deformation behavior of a self-developed zinc based alloy was investigated by isothermal compression test. The results show that the flow stress of the zinc based alloy during isothermal compression decreases with the increase of temperature, and rises with the increase of strain rate; the flow stress of the zinc alloy during isothermal compression can be described by the Zener-Hollomon parameter model.更多还原
