EFFECT OF EXPOSURE TIME AT 250F ON STRESS-CORROSION CRACK GROWTH RATES IN 2024-T351 ALUMINUM

Abstract

The sensitization of 2024-T351 to stress-corrosion cracking after exposure at 250F has been measured using precracked double cantilever beam (DCB) specimens taken in the short-transverse grain direction from 1-in.-thick plate. The susceptibility of the material was assessed by measuring stress-corrosion crack growth rates as a function of the plane-strain stress intensity K(I) in specimens periodically wetted with a 3.5% NaCl solution.
