Surface Structure Modification and Hardening of Al-Si Alloys

Meer over het boek

This reference explores the hardening of material surfaces using concentrated energy flows resulting in the nanostructuring of surface layers. The authors demonstrate how this method achieves a reduction in plastic deformation of the surface, and a more uniform distribution of elastic stresses near the surface during operational use.
