     a 304 stainless steel plate was lap joined to a cp-ti one by friction stir welding technique. stainless steel was selected as the top member. sound dissimilar joints were achieved using an advancing speed of 50 mm/min and rotation speeds in the range of 700–1100 rpm. a region of vortices of bimetallic weld of 304 stainless steel and cp-ti was formed in the lap joint fabricated using the highest applied tool rotation speed; this was associated with plasticizing of both members with the aid of a double-shoulder tool. in addition, due to complex material flow, mechanical interlock features were shaped that consists of extruded stainless steel into the plasticized titanium region. a maximum shear strength value of ∼119 mpa was achieved; this was found to be close to that of cp-ti. the lap joint was strengthened by the formation of vortices of bimetallic weld of 304 stainless steel and cp-ti and mechanical interlock features at joint interface due to complex materials flow.
