Abstract By using in situ X-ray diffraction and profile analysis, the
variations of subgrain size and microstrain in the cold-rolled
SiCAl composite at high temperature were measured, and
the recrystallization behavior of composite was investigated. Test
results show that both of the activation energies of recrystallized
grain growth and matrix recovery at higher temperature are
close to the activation energy for self-diffusion of pure Al, which
verifies that the recovery phenomenon was accompanied with the grain
growth, and the whiskers can not affect the grain growth and recovery
of matrix in composite at higher temperature.
