heal.abstract Surface integrity relates the physical properties of the material and the functional behaviour of a plastically worked surface. Its effect on the formability of high-strength steel sheet, mechanically worked by a low-speed directional process (surface rolling) and by a dynamic stochastic process (ball-drop forming) and thermally stochastically processed by electro-discharge machining, was investigated. Experimentally Forming Limit Diagrams were constructed and inhomogeneity factors were introduced to correlate surface, material properties and microhardness changes to limit straining. In general formability was improved by mechanical processing whilst thermal processing resulted in a poor formability of the sheet for the conditions examined. en
