EFFECT OF QUENCHING RATE ON STRESS-CORROSION CRACK GROWTH RATES IN 2024-T4 ALUMINUM

Abstract

Stress-corrosion crack growth rates in double cantilever beam specimens of 2024-T4 aluminum quenched at two rates from the solution-treatment temperature were compared. The specimens quenched at the slower rate had the faster crack growth rate. This finding agrees with data from other studies in which intergranular corrosion susceptibility was determined by measuring percent loss in tensile strength of preexposed sheet tension specimens.
