Abstract
This work examined the effects of hydrogen on fracture of quenched and tempered 1045 steel. Tests were made at room temperature on tensile, Charpy impact, and 4-point notched bend specimens. This steel exhibits tempered martensite embrittlement (TME) for tempering temperatures between 300 and 375 °C. Thus hydrogen in most cases affected fracture by increasing the amount of intergranular fracture. In bend specimens, hydrogen also induced quasicleavage (QC) fracture at points of maximum normal stress below the notch root, points which appeared to be the locations of crack initiation. Tear ridges on theseQC surfaces were at martensite lath packet boundaries. Crack orientations were largely mode I in uncharged specimens, with mode II appearing at the notch root in most hydrogen-charged specimens. These observations are in general agreement with earlier work on martensitic steel.
