摘要:

采用粉末冶金法将合金元素Ti加到Cu40Zn基体中制备钛黄铜，研究了Ti的添加量对黄铜微观组织、界面结构、相组成以及力学性能的影响。结果表明：Ti在基体中固溶析出并与Cu40Zn反应生成了亚微米级的Cu₂Ti₄O颗粒和Ti纳米团簇，随着Ti含量的提高钛黄铜的屈服强度、抗拉强度和硬度呈提高的趋势。增大位错运动阻力产生的第二相强化、钉扎产生的细晶强化以及加工硬化，使Cu40Zn的力学性能提高。综合性能良好的Cu40Zn-1.9Ti，其屈服强度、抗拉强度、延伸率和硬度分别达到375 MPa、602 MPa、17.7%和163HV。

Abstract：

High strength Ti-reinforced Cu40Zn brass alloy was prepared by powder metallurgy. The effect of Ti addition on the microstructure, interfacial structure, phase composition and mechanical properties of the brass was investigated. Results show that Ti exists in Cu40Zn matrix as sub-micron Cu₂Ti₄O particles and Ti nanoclusters, which can significantly improve the mechanical properties of Cu40Zn by means of second-phase strengthening, fine-grain strengthening and processing hardening. Cu40Zn-1.9Ti has good comprehensive performance: the yield strength, tensile strength, elongation at break and hardness are 375 MPa, 602 MPa, 17.7% and 163 HV respectively.

Key words： metallic materials powder metallurgy brass alloy titanium mechanical properties nano precipitates
