The results indicated that the composite showed quite different strain relaxation before" general" microyielding and its microyield mechanism was not same as that of the matrix alloy. It was also showed that during aging treatment, the microyield strengths of both composite and matrix alloy were dependent to precipitation of the strengthening phase,S', and exhibited a peak aging trend. Thermal cycling treatment could improve the microyield strength of the matrix alloy, but lower the microyield strength of the composite.
