Research Abstract

To widely use friction stir welding (FSW) of steels and titanium alloys in the practical applications, fundamental knowledge on damage mechanism of welding tool during FSW and tool material factors governing tool damage attempted to be obtained. The suppression of the tool damage was achieved by both enhancement of high-temperature strength and distribution of large number of hard phases with average size of 2 to 5 micrometers. The tool material designed so as to meet these requirements exhibited 1.5 times longer tool life than the present tool material.
