Abstract
The hot compression behaviour of AA2014 alloy having 10 wt% SiC particles was studied over a wide range of temperatures (ambient to 400 °C) and strain rates (0.01–10/s). The results were compared with those obtained from identical tests performed on the base alloy to understand the effect of the SiC particle reinforcement. Processing maps were generated using dynamic materials model from the flow stress of the samples. Microstructures of the deformed samples suggest the occurrence of dynamic recrystallization at high temperatures and low strain rate. Flow localization and adiabatic shear bands were observed at higher strain rates and temperatures. The lack of cohesion between SiC particles and the matrix was found to be responsible for the deteriorating deformation behavior of the composite over most of the processing domains. The activation energy for high temperature deformation in the presence of the SiC particles in the alloy was found to be significantly higher than that of the matrix. This makes deformation processing of the composite more difficult than that of the matrix.
