PROFILING THE RESIDUAL STRESS IN 6061Al-15vol. SiC{sub}w COMPOSITE

摘要

The residual stress, RS, profiles in a 6061Al-15vol%SiC{sub}w composite and its alloy matrix were determined by synchrotron radiation diffraction, SRD, at the ESRF, Grenoble, France. SRD could resolve the spatial dependence of all three principal components of the RS field. The origin of the macro stress could unambiguously be identified as the parabolic temperature gradient present during quenching and a confirmation of many theoretical works could be given.
