To evaluate the potential of 2091 sheet material the alloy was heat treated to three different underaged tempers. Mechanical properties were determined by tensile, fracture toughness, and fatigue crack propagation tests. Stress corrosion susceptibility and other corrosion properties were investigated. The results showed that advancing aging improves tensile and SCC properties but deteriorates fracture toughness and general corrosion behaviour.
