The effects of Ti and Sn alloying elements on precipitation strengthened Cu40Zn brass using powder metallurgy and hot extrusion

► Alloying elements Ti and Sn are proposed as additives in 60/40 brass. ► Super-saturated Ti in powder creates high chemical potential for precipitation. ► Ti is readily segregated in primary particle boundaries in BS40-1.0Ti. ► Sn was proposed as an additive to inhibit segregation of Ti in BS40-1.0Ti. ► The introduction of Sn to BS40-1.0Ti brass effectively impedes Ti segregation.
