- Available for pre-order. Item will ship after December 15, 2020
Surface Structure Modification and Hardening of Al-Si Alloys explores the hardening of material surfaces using concentrated energy flows resulting in the nanostructuring of surface layers. The authors demonstrate how these methods achieve a reduction in plastic deformation of the surface, and a more uniform distribution of elastic stresses near the surface during operational use significantly reducing part failure. It presents results from research, and scientific and technological enterprises involved with modification of light alloy surfaces for use in the automobile and aero-space industry.
Additional key features include:
- Addresses theoretical and experimental research computer simulation of structural phase transformations at the nanolevel to create new materials.
- Details and compares electroexplosion alloying, electron beam processing and electron-plasma alloying of an Al-SI Alloy.
- Explains multiphase plasma jet treatment to obtain high-quality coatings with good and high functional properties.
This reference is a valuable resource for specialists in the field of physical material science, condensed state physics, metal science and thermal treatment and will be of interest to undergraduate and post-graduate students in these fields.
