Study on Thermal Simulation of a New Al-Mg-Si-Cu Alloy
The new Al-Mg-Si-Cu aluminum alloy has been developed for application in cold and hot extrusion and forging. Its nominal composition is 1.37%Mg、0.85%Si、0.82%Cu、0.11%Cr and 0.15%V. In this paper, The hot deformation behaviors of the new Al-Mg-Si-Cu aluminum alloy were studied by means of compression deformation tests on MMS-200 multifunctional materials simulation machine at strain rates ranged between 0.1~0.5s-1 and deformation temperature between 350~550°C. The laws of the flow stress dependent both on thedeformation temperature and strain rates were discovered, and then the relationship between the first peak-stress σp and strain rates was obtained through one-dimensional linear regression.
