| Abstract: | The composition of new complex aluminum-bronze alloy containing Mn was determined in this paper. The effect of microalloying both V and B and the heat treatment on its hardness and mechanical properties of aluminum-bronze alloy were studied. A yield strength of 985 MPa and elongation of no less than 18% were obtained for the alloy when quenched after soading for 1 hour at 820 ℃.No spark or explosion would be induced when it was intensively stroked and worn.The anti-explosion tools made by the alloy did not cause deformation and fracture when used. |
