Rolling and Annealing Textures of SiCw/Al Composite


Article Preview

A squeeze casting 15vol.%SiCw/Al and pure aluminum were cold rolled to 50 pct reduction in thickness and then annealed at 500°C for 1h. The textures of the treated materials were examined using XRD. The dominant texture components in the cold rolled composites consisted of {112}<111>、{100}<011> and {123}<634> and were much weaker than those in the cold rolled aluminum. The new texture components in annealed composites were {211}<213>、{013}<131> and {011}<211> and had the similar intensity as those remained from the deformation state. This indicated that the recovery reaction and recrystallization occurred simultaneously when the cold rolled composite was annealed at 500°C. Also, the annealing texture was much weaker in the composite than that in the aluminum. The weaker deformation and annealing textures in the composites can be attributed to the introduction of the whiskers.
