Other AbstractThe mechanical property parameters of original O-state and short-time heat-treated sheets for 2 B06 aluminum alloy were obtained by uniaxial tensile test. Then,the application of local heat treatment tailored heat treated blanks( THTB) in the two-pass hydroforming of aluminum alloy frame parts was simulated and verified by the finite element simulation method,and the mechanism of improving the forming ability of parts was analyzed. The simulation results show that when the original O-state sheets are used to form the frame parts,the local thinning is serious,and the rupture danger zone mostly occurs in the plane strain region. Therefore,a reasonable local heat treatment scheme makes the sheet have a gradient distribution of soft and hard materials,which significantly improves the forming ability of frame parts. Furthermore,the process parameters of laser heat treatment were determined by the laser experimental temperature measuring device,and the sheet coated with the water-based graphite heat treatment zone is heat treated to make it the THTB. Finally,the THTB is hydroformed twice to verify the accuracy of the simulation.
