预变形促进基体t1相析出，并使其显著细化和均匀分布。
The plastic deformation could promote matrix T1 precipitation and make it refined and uniformly distributed.
材料经固溶处理后析出物绝大多数都溶入基体。
Most precipitate dissolve into the matrix after solution treatment.
增强体的加入既能加速时效前期沉淀析出又可加快时效后期复合材料的软化，但不改变基体沉淀相的析出顺序，而只影响其析出速度。
Addition of mullite short fibre can accelerate precipitation in early aging stage and speed up composite's soften rate in later aging stage, but not alter the precipitation sequence in matrix.
