...Abstract Abstract The relationship of stress and strength gradients must be considered simultaneously in analysis of a particular type of fracture. This chapter discusses the principal elastic stress distribution in members of various shapes under different types of pure loads. A basic...

It describes how cooling rates, temperature gradients, and local concentrations influence the topology of the crystallization front, and how they play a role in determining the morphology and dispersion degree of the grains observed in cross sections...

... the characteristics of the metals themselves. All fractures are caused by stresses, and a version of the “weakest link” theory applies: fracture will originate wherever the local stress (load per unit of cross-sectional area) first exceeds the local strength. This location will vary depending on the strength...

What is the relation of the fracture direction to the normal or expected fracture directions? The direction of a fracture usually has a specific relation...

The addition of the carbonitrided surface increases the case residual-compressive stress level and thus improves contact fatigue resistance as well as increases the case strength gradient. When the carburizing/carbonitriding processes are used together, the ratio of effective case depth...

Core strength and associated properties (e.g., toughness) are regarded as important to the overall strength of a case-hardened part. Core strength is controllable within limits, for which a tensile strength range...
