摘要：
This work examined 1045 steel. Tests were made at room temperature on tensile, Charpy impact, and 4-point notched bend specimens. This steel exhibits tempered martensite embrittlement for tempering temperatures between 300 and 375 degree C. Hydrogen affected fracture by increasing the amount of intergranular fracture. In bend specimens, hydrogen also induced quasicleavage fracture at points of maximum normal stress below the notch root.
