摘要: Laser surface treatment of Rene 41 high-performance alloy is carried out with the presence hard particles at surface. B4C and SiC are uniformly distributed within 40 µm carbon film workpiece prior to laser process. The effect on residual stress microhardness variations investigated treated Morphological metallurgical changes in layer examined by using electron microscopy, energy dispersive spectroscopy, X-ray diffraction. Residual formed determined from data. It found that free asperities such as large size voids cracks. A dense region, which causes volume shrinkage while contributing enhancement result highest surface, attributed its high thermal expansion coefficient. Copyright © 2013 John Wiley & Sons, Ltd.
