Abstract
The hot deformation behavior of 15vol% SiCp/Al composite has been studied with thermal simulation compression test in the temperature range of 623-773 K and strain rate range of 0.001-10 s-1. Based on Murty criterion, the hot processing maps have been established, and a critical instability strain map has been drawn accordingly. It can be found that with the increased deformation temperature, the strengthening mechanism of SiCp/Al composite decreased and softening mechanism enhanced gradually. Based on the critical instability strain map, two suitable regions for SiCp/Al composite materials hot processing have been identified, namely in deformation temperature range of 700-773 K, strain rate range of 0.001-0.01 s-1, and deformation temperature range of 740-773 K and strain rate range of 0.02-0.14 s-1.
