メカニカルアロイングしたCu-Ti-B合金粉末の真空ホットプレスによる固化成形特性

抄録

Cu-9Ti-18B alloy powder was prepared from elemental copper, titanium and boron powders by mechanical alloying for various milling times and hot-pressed in vaccum (VHP). The structural change in the alloy with VHP time was examined and mechanical strength and electrical resistivity of the alloy compact by VHP were also examined. The compactibity in VHP of mechanically alloyed powder was estimated. The density in the alloy compact mechanically alloyed with long milling times were nearly equal to the calculated value. The flexure strength in 3-point bending, hardness and electrical conductivity of the alloy compacts increase with VHP time. These increases are marked in VHP of the alloy powder mechanically alloyed for a long time.
