Abstract: The soundness of the metallurgical structure and the associated strength of a forged powder preform material increase with increasing lateral flow during the forging process. Unconstrained lateral ...

Abstract: The process of ductile fracture during metalforming was modeled by deforming plasticine specimens which contained steel-wire segments to simulate the inclusions in a fully plastic matrix. Due to ...

Abstract: All previous analyses of the minimum gauge problem either fail to arrive at a criterion for determination of the minimum gauge or result in predictions which are grossly in error. The basic ...

Abstract: The basic deformation and fracture behavior of sintered powder materials was determined through simple compression tests for application to powder forging processes. Tests were carried out on an ...

Abstract: A method is presented for the determination of the lateral distribution of pressure in thin strip rolling. A simplified three-dimensional analysis of elastic deformation of the rolls is developed ...

Abstract: A study was conducted of the metal flow and fracture in a forging process involving both extrusion flow into a hub and lateral flow into a flange. In the initial stage of deformation, ...

Abstract: Fracture under combined stresses has been studied with the objective of evaluating existing fracture criteria and providing data for the formulation of new criteria. Upsetting, bending, rolling, ...

Abstract: Bend tests under superimposed hydrostatic pressure were carried out on a low carbon steel containing globular sulfide inclusions to investigate the variation of ductile fracture and forming limits ...

Abstract: Efficient, defect-free manufacturing of high-temperature superconducting (HTS) wires and tapes is critical to a variety of defense and electrical power applications. To contribute to the improvement ...
