Abstract

Environmentally assisted cracking tests were performed using 3.5 NiCrMoV low alloy steel in deionized water containing 100 ppb dissolved oxygen at 333K. Effects of strain rate, strain hold time and superposed vibratory stress on crack initiation and propagation were investigated. Slower strain rate, longer strain hold time and larger superposed vibratory stress enhanced damage and resulted in shorter life. Effect of each factor on the reduction of life was obtained. The crack morphology was transgranular and widened by corrosion.
