摘要 Al alloy reinforced with SiCp was fabricated by the method of pressureless infiltration.The effects of factors such as SiCp size,volume fraction,matrix material and heat treatment process on microdistortion behavior of Al alloy were investigated.The results show that microdistortion decreases along with lessening of SiCp size and increasing of SiCp volume fraction.Matrix material has influence on the microdistortion behavior,and solution-aging can improve the microdistortion behavior.Stress and residual strain related to microdistortion behavior were simulated by FEM.It is found that the distribution of strain and stress is not symmetrical; residual strain and stress at interface are higher than those at the other places;at the sharp-angled area of a particle,matrix has the highest strain and stress where plastic distortion is caused at first;the microdistortion and stress far from the interface are smaller.

The results show that microdistortion decreases along with lessening of SiCp size and increasing of SiCp volume fraction. Matrix material has influence on the microdistortion behavior, and solution-aging can improve the microdistortion behavior. Stress and residual strain related to microdistortion behavior were simulated by FEM. It is found that the distribution of strain and stress is not symmetrical; residual strain and stress at interface are higher than those at the other places; at the sharp-angled area of a particle, matrix has the highest strain and stress where plastic distortion is caused at first; the microdistortion and stress far from the interface are smaller.
