摘要：
Significant tool wear manifested as submicron tungsten-rich particles was observed in the workpiece after friction stir processing (FSP) of investment cast Ti-6Al-4V on both the surface and in the bulk of the stir zone. The tool was manufactured from a tungsten alloy, which stabilizes the β phase and can locally suppress the β transus. A postprocessing α/β heat treatment was performed to demonstrate the microstructure effects of tungsten dissolution.
