... is accomplished by nonsymmetrical radial metal deformation. The size of internal cracks is likely to be greater under these conditions than when swaging is accomplished in a more uniform symmetrical reduction, such as by rotary swaging or press swaging. Corrosion then combines with the internal stress to cause...

These inclusions are not plastic or deformable at typical hot working temperatures and retain their globular shape. Therefore, they are less injurious with respect to ductility, toughness, and fatigue life in finished...

Abstract The discussion on the fracture of solid materials, both metals and polymers, customarily begins with a presentation of the stress-strain behavior and of how various conditions such as temperature and strain-rate affect the mechanisms of deformation and fracture. This article describes...
