抄録	The super-saturated solid solution of Ti in water-atomized BS40-1.0Ti (Cu-40wt%Zn1.0wt%Ti) brass powder creates a high chemical potential for the precipitation reaction. However, Ti readily segregates in the primary particle boundaries at elevated temperatures, which detrimentally affectes the mechanical properties of the extruded BS40-1.0Ti brass via powder metallurgy (P/M). Accordingly, Sn was proposed as an additive in BS40-0.6Sn1.0Ti (Cu-40wt%Zn0.6wt%Sn1.0wt%Ti) to inhibit Ti segregation. Consequently, the Ti precipitates were retained as CuSn₃Ti₅ compound in both interior grains and grain boundaries rather than in the primary particle boundaries. This result demonstrates that Sn addition can effectively obstruct Ti segregation in the primary particle boundaries, and showed a significant grain refinement and mechanical strengthening effect on BS40-0.6Sn1.0Ti brass.
