Title: Characteristics and pressing-sintering process of Cu-Zr powder formed by high-energy ball milling
Abstract: Cu-Zr powders were prepared by high-energy ball milling the Cu and Zr elemental powders.The mechanical alloying process and the powder characteristics were studied by means of SEM and XRD and the pressing-sintering process of the milled powders was also preliminarily studied.The results indicate that during ball milling,Zr atoms and Cu atoms form supersaturated solid solutions and Cu-Zr alloy intermetallic compound.The morphology of the milled powders are of near ball shape different from the platelike shape of the powders at the early milled stage.Meanwhile,the microhardness of the milled powders increases with the milling time.As for the Cu-Zr powder ball milled for 15 hours,much higher pressure is required to obtain a higher pressing density duo to powder hardening in the ball milling process.
