Abstract : This paper reports on hardness distribution and microstructure evolution in friction stir welded(FSW) Al6061-TiB2
in-situ metal matrix composite processesd by stir casting technique. Composite plates were butt welded using FSW3T friction
stir welding machine under optimized process parameters. Results show an higher micro hardness in the stir zone and parent
zone where as a lower microhardness in heat affected zone. Optical micrographs reveal an extensive grain refinement and
homogeneous re-distribution of fine TiB2 particles in the stir zone and formation of coarse precipitates with grain growth in the
heat affected zone.
