Heat treatments are frequently used to modify the microstructure and mechanical properties of materials according requirements their applications. Laser surface treatment (LST) has become a relevant technique due high control parameters localization involved in modification. It allows for rapid transformation near surface, resulting minimal distortion workpiece bulk. LST encompasses, turn, lase...

A comprehensive review of fatigue behavior and fatigue design of heavy section wind turbine castings made of ductile iron EN-GJS-400-18-LT is performed. Common metallurgical defects that are affecting fatigue behavior of this material were studied. Review of different researches on quantitative effect of chunky graphite and micro structure on fatigue behavior of EN-GJS-400-18-LT was perform...
