Cu-8.0Ni-1.8Si-0.15Mg (wt.%)合金样品的热变形在Gleeble-1500热模拟器上进行，在不同变形温度下采用不同的应变速率。计算了热变形活化能Q，建立了热压缩本构方程。金相显微镜用于分析合金在变形过程中的微观结构演变。加工硬化、动态回复和动态再结晶对合金在不同温度区的塑性变形行为具有重要影响。合金的加工图已经建立。 (C) 2010 Elsevier B.V. 保留所有权利。
The hot deformation of Cu-8.0Ni-1.8Si-0.15Mg (wt.%) alloy sample was carried out on a Gleeble-1500 thermo-simulator with various strain rates at different deformation temperatures. The thermal deformation activation energy Q was calculated and hot compression constitutive equation has been established. Metallomicroscopy was employed to analyze the microstructures evolution of the alloy during deformation. The working hardening, the dynamic recovery and the dynamic recrystallization play important roles to affect the plastic deformation behaviors of the alloy at different temperature regions. The processing map of the alloy has been established. (C) 2010 Elsevier B.V. All rights reserved.
