摘要
The elTcct of different dimension stabilization treatments on the dimension stability of SiC_(p)/Al composites were investigated by the measurement of microyield strength,microcreep properties,dimension,residual stress and analyses of transmission electron microscopy.Results show that the heat cycle dimension stabilization techniques could efficiently decrease the residual stress,stabilize the dimension change,and increase resistance to microplastic deformation.The main reason was that the heat cycle dimension stabilization techniques might form stable dislocation structure in the SiC_(p)/A1 composites.
