原始语种摘要: Abstract(#br)2.9 mm thick 20 wt% B 4 Cp/6061Al-T6 composite sheets were friction stir welded using a threaded cermet tool at welding speeds of 50–400 mm/min and a tool rotating rate of 1000 rpm and then subjected to post-weld artificial aging. Sound joints were achieved under all welding speeds. The threaded cermet pin only exhibited slight abrasion at the top thread of the screw after all of the welding operations with a total length of 1200 mm. The B 4 C particles were blunted and fragmented, and uniformly distributed in the nugget zone (NZ), due to the severe material deformation combined with the particle/pin interaction. The fine precipitates in the matrix alloy were mostly dissolved in the NZ but were significantly coarsened in the heat affected zone (HAZ). The joints exhibited...
