摘要：
Effects of static annealing on post-deformation properties and cavitation are examined in the Si3N4p/Al-Mg-Si composite and the mechanisms of cavity shrinkage by static annealing are investigated. Post-deformation tensile properties were sufficiently recovered by static annealing. However, many small cavities still remained in the annealed samples. This map be attributed to the lower mass transfer rate by interface diffusion.
