摘要
Influence of heat treatment on mechanical properties and tribological behaviors of Ti and B modified wrought aluminum bronze were studied. The results show that different strength and plasticity combination of the alloy after solution treatment can be obtained by adjusting the ageing temperature. When aged at 450?℃, the tensile strength σ b, yield strength σ 0.2 , elongation 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 lubrication condition with pressure above 22.2?MPa, alloy with low temperature ageing has the best wear property. However, under the condition involving impact or shock loading, alloy with high temperature ageing is preferable. If the load is not heavy, the alloy under extrusion state is favorable for wear resisting parts.
