Abstract:

ABAQUS software was used to 3D model and simulate the quenching process of 7075 aluminum alloy profiled plate. With the secondary development of the software, the influence of quenching medium, quenching direction and quenching speed on the residual stress and quenching distortion of the profiled plate were studied. The simulation results show that UCON quenching solution with 10% concentration can reduce residual stress by 50.1% compared with water quenching. The residual stress is the smallest when the quenching direction is perpendicular to the plane of the profiled plate, and the quenching distortion is related to the quenching direction. The data show that the faster the quenching speed in a certain range, the reduction of residual stress is more significant.
