Deformation and microstructural development in a 2124Al/SiCpMMC during high strain rate superplasticity

Abstract:

Both superplastic deformation and the accompanying microstructural development in st 2124Al/18vol%SiCp, metal matrix composite have been investigated. Mechanical property results comparable to those found in similar materials have been achieved, the optimum superplastic elongation being 430% at a strain rate of almost 0.1s(-1) . The anomalously high activation energy which has been observed in other studies was also reproduced. Differential scanning calorimetry showed that the optimum tempera...
