Quench Sensitivity in A1-Cu-Li Alloys

Abstract

A study has been performed to characterize the quench sensitivity of an aluminum-copper-lithium alloy, 2090. The mechanical properties were evaluated from samples subjected to different quench conditions and heat treatments. Transmission electron microscopy (TEM) was used to examine the microstructural characteristics of the alloy. The results are described with respect to correlations between microstructural characteristics and strength. A range for the critical quench rate of alloy 2090 has been established. The effect of quench sensitivity on hardness and conductivity is also discussed. Keywords: Aluminum alloys; Copper alloys; Lithium alloys; 2090 Aluminum; Quench sensitivity; Cooling profiles. (KT)
