The effects of Ti and Sn alloying elements on microstructural and mechanical properties of the precipitation-strengthened brass by powder metallurgy

摘要

Widely used α+β brasses have the best combination of high technological and service properties. In this study, Ti and Sn were proposed as alloying elemenfe additions to the Cu40Zn brass in viewpoint of alloy designation and processing method by powder metallurgy. The microstructure, phase transformation, precipitation behavior and mechanical properties of the Cu40Zn with Ti and Sn pre-alloyed P/M materials were investigated in detail.
