| Abstract: | AL2 O3/AL alloy composites are manufactured by squeeze casting and the interfacial stability and the tensile strength of the composites are studied at high temperature. The results indicate that the chemical reactions which are favourable to the combination between the fiber and the matrix occur on the interface between the fiber and the matrix in AL2 O3 /ZL109 composites, and the structures of the interfacial layer are stable at high temperature. Compared with the matrix alloy,AL2 O3 /ZL109 composites have better high temperature tensile strength and the working temperature is over 100t. In addition, the failure forms of AL2 O3 /ZL109composites at high temperature tension are analyzed. |
