Compression testing of a SiCw/Al composite at temperatures close to and above the solidus of the matrix alloy

Hot compression behaviour of a 20 vol.% SiCw/6061Al composite was determined at temperatures close to and above the solidus of the matrix. Work hardening behaviour of the composites was analyzed by whisker redistribution and breakage during deformation. Temperatures above the solidus of the matrix were suggested for the plastic forming of the composites.
