Abstract : This report presents the findings of a scanning electron microscope study of the tensile, fatigue, and impact fracture characteristics of a carbon steel; two high-strength, low-alloy steels; and a high-strength steel weldment. Tension and fatigue specimens were tested in as-received, hydrogen-embrittled, and temper-embrittled conditions, while impact specimens were tested in the as-received condition only. The failure mode of embrittled and unembrittled weldments containing induced weld defects was also studied.
