Abstract
Aluminum foam composite of aluminum alloy die casting ADC12 coated by pure aluminum A1050 was fabricated by friction stir welding (FSW) route precursor foaming method. Moreover, weight drop impact compression tests of the aluminum foam composites were carried out. We attempt to estimate the plateau stress of the aluminum foam composite based on the mean compressive stress on a maximum-porosity cross section perpendicular to the direction of compressive loading. Through the comparison of impact compression test results with the estimated results, it was expected that the plateau stress of the aluminum foam composite can be evaluated when the equivalent diameter of pores in ADC12 region is approximately equal to that of ADC12 uniform porous aluminum.
