MATERIAL PROPERTIES FOR SHEET FORMABILITY
The material properties of work-hardening behavior, anisotropy, strain-rate sensitivity and ductility are discussed in relation to sheet formability and the scope for improving forming properties through these variables is considered. It is shown that the scope for improvements through increasing the sustained work-hardening capacity and the anisotropy is useful but subject to natural limitations. Strain rate effects in pressing operations are not controlled mainly by the material but by process considerations. Ductility is dictated by the inclusion content of the material and the improvement of material cleanliness is the most important means of raising quality and performance. The forming and subsequent properties of high strength sheet materials are briefly reviewed and here especially the inclusion content is of major importance.
