摘要：

Stress corrosion cracking of Al-2. 7 percent Li-1. 2 percent Cu-0. 9 percent Mg-0. 14 percent Zr alloy in 3. 5 percent NaCl aqueous solution was investigated. As this alloy showed a two step hardening behavior by aging at 180 degree C, under-aging, peak-aging at first stage, peak-aging at second stage, and over-aging were selected as typical aging states. Superior SCC properties were found in the state of peak-aging at first stage, peak-aging at second stage, under-aging and over-aging in that order. SCC resistance was inferior to 7475 alloy in higher stress or in higher stress ratio, but in lower stress ( less than 30 kg/mm**2) or lower ratio ( less than 75 percent sigma //0//. //2) the resistance increased to be comparable to that of 7475. Anodic dissolution seemed to be a dominant factor in SCC.
