Workability Theory and Application in Bulk Forming

Abstract

Workability is a characteristic of the material/process system. The role of the material is measured by a simple test or tests and should be expressed in a quantitative form that is applicable universally. This measure is taken to be a basic property of the material composition and structure, and it reflects the macroscopic outcome of the micromechanisms of plastic flow perturbed by such inhomogeneities as voids, inclusions, and grain boundaries. Such phenomena are dependent not only on the material structure but also on the process parameters (strain rate and temperature), which define the role of the process in determining workability. 6061 mentioned ~17 times in tables and text. 6061 forging example showing internal fracture in two figures.
