Metal Forming Mechanics and Metallurgy

This text provides an understanding of the interaction of the tooling and metal during plastic deformation (mechanics) and a discussion of the important metallurgical factors. After a review of stress, strain, yield criteria and strain hardening, the concepts of instability and effects of temperature and strain rate are treated. Several methods of analysis are covered and applied to operations including extrusion, rolling, drawing and forging.;The text provides general conclusions about the effects of the deformation zone geometry and metallurgical considerations important to bulk forming. A section on sheetmetal forming, covering bending, residual stresses, plastic anisotropy, deep drawing and stamping and the metallurgical considerations relevant to those processes is included. The authors also present an approach to upper-bound analysis, combining the slab force balance and a slab-energy contribution, and cover the effect of processing parameters on the inhomogeneity of plastic instability.
