Probabilistic Fracture Resistance of a Forged Quality Medium Carbon Alloy Steel

Article Preview

Abstract:

Impact and fracture toughness of a large number of medium carbon alloy steel specimens have been ascertained using standard ASTM procedures, apart from examining their chemistry, microstructure, cleanliness, tensile behaviour and fracture surfaces. The results indicate that the scatter associated with ductility, impact and fracture toughness is considerable unlike that for strength or hardness. Analyses of the role of undesirable elements on toughness properties indicate that the scatter associated with fracture resistance of the steel primarily originates from the amount of tramp elements.
