摘要

In this work,the current understanding and development of friction-stir welding and processing of Ti6Al-4V alloy are briefly reviewed.The critical issues of these processes are addressed,including welding tool materials and design,tool wear,processing temperature,material flow,processing window and residual stresses.A particular emphasis is given to microstructural aspects and microstructure-properties relationship.Potential engineering applications are highlighted.
