摘要

The effect of static strain ageing on the tensile and fracture toughness properties of a Carbon-Manganese steel has been investigated. A uniform 2% pre-strain has been applied to tensile specimens and its equivalent has been achieved at the crack tip of notched specimens by loading them elastically to 60 MPa√m. Analyses of the data showed that strain ageing brought about a significant increase in the yield stress and a change in the shape of the fracture toughness curve.
