Abstract:The effect of different dimension stabilization treatments on the dimension stability of SiCP / 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 techmques could effciently 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 farm stable di-siocation structure in the SiCP / Al composites.
Key words: dimension stabilization SiCP / Al composite stable dislocation structure
