| 英文摘要 | Hot deformation mechanisms of 2009Al (Al-4.0 wt% Cu-1.5 wt% Mg) alloy and 17 vol% SiCp/2009Al composite prepared by powder metallurgy (PM) route were investigated using isothermal compression test at temperatures from 350 to 500 & DEG;C and strain rates from 0.001 to 1 s-1. Strain rate sensitivity map, temperature sensitivity map and processing map based on modified dynamic materials model (MDMM) were constructed to study the deformation mechanisms by combining with microstructural examination. The temperature sensitivity curves gave an identical equicohesive point, which was a strong and weak transition point of grain boundaries relative to grains, (Teq) of 450 & DEG;C both for the composite and unreinforced alloy. At high strain rate of 1 s-1, dynamic recovery (DRV) and partial dynamic recrystallization (DRX) were the dominant mechanism, while at low strain rate of 0.001 s-1, DRX was the dominant mechanism. The SiC particles accelerated dislocation multiplication and impeded the restoration below 450 & DEG;C. The instability criteria based on Ziegler's continuum principle and Lyapunov function were not applicable for the PM composite and the unreinforced alloy. |
