“…Some studies on the machinability of intermetallic compounds have been reported for the Ti-Al system and the Fe-Al system, including a diphase material of Ti 3 Al and TiAl (5) , a diphase material of Fe 3 Al and Fe 3 AlC 0.5 (6) and a Ti 3 Al-TiAl laminar material (7), (8) . From these studies, it has been clarified that a cemented carbide K type tool is superior to the P type tool for machining a diphase * Received 31st August, 2005 (No.…”

The intermetallic compound Fe 3 Al was processed by a reactive sintering process, and its machinability from the viewpoint of tool wear was investigated using dry turning. In cutting Fe 3 Al with a cemented carbide tool, the tool life was approximately one tenth that of cutting carbon tool steel SK3 because of intense flank wear. The tool life for cutting Fe 3 Al using the cemented carbide P20 (WC-TiC-TaC-Co) tool was longer than for cemented carbide K10 (WC-Co). In addition, a cermet tool reached its tool life limit by chipping for the whole cutting speed range measured. The roughness of the machined surface of Fe 3 Al cut using a cemented carbide tool was much smaller than for SK3. However, for cutting using the cermet tool, the roughness showed a sharp rise due to chipping. It was found that the wear rate of the WC particles in the tool material is larger than TiC particles. The results of the study suggest that the cemented carbide P20 is suitable for cutting Fe 3 Al.
