. Table 1 Physical properties of 1.0%Al2O3/Cu composite before and after rolling Fig.5 shows the curves of stress-strain relationship. From the curves we can read that the tensile strength of 1.0... is about 250 MPa, while the curve of Fig.5(b) has no yield platform. This proves the composite before rolling possesses better ductility than the composite after rolling. Fig.5 Stress-strain curves......
