Investigation on Quench Sensitivity of a Heat-Resistant Aluminum Alloy

Abstract:

The quench sensitivity of 2D70 aluminum alloy was investigated by end-quenching. The effect of water temperature on quench sensitivity was studied by measuring the hardness and conductivity. The end-quenching characteristics of hardness and conductivity of 2D70 aluminum alloy under different water temperatures has been described. The end-quenching characteristics of 2D70 and 2124 alloy under the same condition have been compared and analyzed. The results show that the susceptibility of 2D70 alloy to quenching is slow and the differential effects of the water temperatures of 16°C and 30°C on end-quenching of this alloy are not obvious. The quench depth of the alloy is more than 150mm.
