抄録	In this paper, the uniform distribution process of bismuth particles in Cu-40Zn brass alloy by powder metallurgy (P/M) and machinable lead-free P/M brass with bismuth are described. Cu-40Zn Brass with bismuth powders produced by the rapid solidification processing were used as raw materials, having mean particle sizes of 150 μm. Three kinds of billets were prepared for the extrusion, namely green compact, sintered billets by using spark plasma sintering (SPS) and cast ingot. Bismuth dispersed in brass powder formed grains and dissolved into the powder surface by the heat treatment at the temperature over the melting point of bismuth. The behavior of bismuth existing in the primary particle boundary caused a decrease in the elongation of the extruded brass. Drill cutting ability was improved for the extruded material with the continuous machining chip. The shape of the machining chip was affected by the combination of brass matrix and the distribution of bismuth.
