摘      要：AA 6061 alloy and interstitial-free(IF)steel plates were joined by the friction stir welding(FSW)method,and the microstructure,mechanical properties,and biaxial stretch formability of the friction stir welded(FSWed)parts were *** results indicate that the FSWed parts showed optimum tensile strength during FSW with the 0.4-mm offset position of the *** Fe4Al13 intermetallic compound formed in the defect-free intersection of AA 6061 and IF-steel plates during *** hardness of the IF-steel part of the FSWed region increased almost 90%relative to its initial hardness of HV0.2 *** tensile and yield strengths of FSWed regions were approximately 170 MPa and 145 MPa,*** to the formability tests,the Erichsen Index(EI)of the IF-steel,AA 6061,and the FSWed samples were determined to be 2.9 mm,1.9 mm,and 2.1 mm,*** EI of the FSWed sample was almost the same as that of the AA 6061 ***,it decreased compared with that of the *** force at EI(FEI)was approximately 1180 N for the FSWed *** value is approximately 70%higher than that of AA 6061 alloy.
