Austempered ductile iron (ADI) has been proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness combined with good wear resistance and machinability. These properties can be achieved upon adequate heat treatment which yields the optimum microstructure for a given chemical composition. The heat treating of the ductile cast iron produces th...

This work deals with the feasibility of obtaining Austempered Ductile Iron with Dual Phase structures (DPADI) through heat treatment, starting from different as-cast microstructures. The mechanical properties on these microstructures were evaluated. DPADI microstructures were obtained by adding different tenors of silicon (2.4% to 4.2%) to the melts and keeping the other alloying elements const...

Ductile Cast Iron is a widely used cast iron. iron applications are in various sectors of modern mechanical industries. has wide uses the field car industry, military industries, agricultural equipment, construction and mines. The production ductile faces many technical difficulties our local factories due to difficulty providing equipment technologies for its by common methods. In this study, ...

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. ...

The influence of aluminum, within the range of 0.08 - 6.16 wt.%, on the microstructure and hardness of as-cast ductile cast iron has been studied. A number of irons of different composition have been made by green sand casting and gravity die casting of appropriate design to provide the experimental materials. It has been found that Al addition and higher cooling rates in permanent mould castin...

The concept for geological disposal of nuclear waste and spent nuclear fuel relies on a multi-barrier system with the copper/cast iron canister as the first barrier. The canister is designed to retain its integrity for at least 100000 years, which means that future glaciations need to be considered. A thick ice block together with hydrostatic pressure from groundwater would produce hydrostatic ...
