Effects of Surface Roughness Microtopography on Formability in Cold Rolled Steel Sheet

Abstract:

The surface roughness morphology of cold rolled sheet treated with three coarsen processes, including shot blasting texturing, electro-discharge texturing and laser texturing, was examined and analyzed before and after stamping. The influence of the micro-topography on the plastic deformation behavior during forming was then discussed. The results revealed that the sheet with uniform dispersion micro-pit, large concave valley and smooth convex hull exhibits a good forming performance.
