| Abstract: | Influence of heat treatment on mechanica l properties and tribologica l behaviors of Ti and B modified wrought aluminum bronze were studied. The res ults show that different strength and plasticity combination of the alloy after solu tion treatment can be obtained by adjusting the ageing temperature. When aged at 45 0 ℃, the tensile strength σb, yield strength σ0.2, elongatio n δ and hardness of the alloy are 1 050 MPa, 780 MPa, 4.5%, HB282, respectively. When aged at 650 ℃, those of the alloy are 905 MPa, 600 MPa, 12%, HB232, respectively. Under boundary l ubri cation condition with pressure above 22.2 MPa, alloy with low temperature agei ng has the best wear property. However, under the condition involving impact or sh ock loading, alloy with high temperature ageing is preferable. If the load is no t heavy, the alloy under extrusion state is favorable for wear-resisting parts. |
