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...
In this paper, the reasons of damage water pumps parts of the air compressor cooling system were studied. To reach this goal, the works like preparing metallographic samples, evaluation of structure, investigation of mechanical properties, the alloy parts detection and chemical analysis of deposit and corrosion products collected from the parts were performed. According to studies and results o...
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 performed. ...
In this present work effect of temperature and graphite contents on the microstructural and mechanical properties of iron based powder metallurgy freeform was studied. The different graphite contents (0%, 2%, 5% and 10%) were mixed in iron powder and compact them in 100 KN. These specimens were sintered at 7000 C, 8500 C and 10000 C in muffle furnaces. Microstructural properties were evaluated ...
