Abstract

Abstract: 4343/3003/4343 aluminum alloy composite plate is widely used in the heat transmission. It is commonly compounded by hot rolling, however, the microstructure uniformity of the alloy after hot rolling is disappointing, which is very unfavorable to the subsequent cold rolling. Therefore, it is necessary to establish a reasonable heat treatment process for the hot rolled composite plate. The effect of heat treatment process on the microstructure of the 4343/3003/4343 aluminum composite plates was studied by means of optical microscope and scanning electron microscope. The results show that the annealing temperature, annealing time, and cooling rate after hot rolling have significant effects on the microstructure of the composite plate. Increasing the annealing temperature, prolongating the annealing time, and slowing down the cooling rate after hot rolling are beneficial to the polymerization/coarsening of the precipitate in the composite plate, but longer annealing time will lead to the redissolution of precipitation, which is not conducive to subsequent cold rolling processing. According to the experiment and theoretical analysis, the optimal heat treatment process is obtained as follows: annealing at about 500 ℃ for about 4 h, and preferring water cooling after the hot rolling.
