| Abstract: | The effects of reciprocating extrusion on microstructuer and properties of AgMg3 alloy were investigated by metallography observation,microhardness test,scanning electron microscopy analysis and mechanical test. The results show that the grains of AgMg3 alloy can be effectively broken,grain size significantly refined and the mechanical properties significantly enhanced by reciprocating extrusion. After reciprocating extrusion,the tensile strength,reduction of area,and elongation of the AgMg3 alloy are all i... |
