The aim of this study was to determine the correlation between size and distribution microstructural constituents their cooling rate, as well mechanical properties rate AlSi9Cu3 aluminum alloy when cast in high-pressure die casting (HPDC) conditions. In other words, ultimate goal research for a at different rates. Castings with wall thicknesses were chosen, rates assumed each one. from industri...

The work is devoted to the problem of an increase in proportion scrap metal castings smelted and produced from wear-resistant chromium cast irons. Castings obtained with more than 60% armor cracked during solidification subsequent heat treatment were selected as research objects. similar mill after operation characterized different wear resistance compare characteristics structure properties. c...

Carbonate reservoirs are rich in oil and gas reserves; thus, they have great exploitation potential. Therefore research on the microscopic mechanisms of carbonate is significance. Based thin section images core castings typical Well 555 its pore fracture features actual reservoirs, this study designed three kinds representing throat structure real rocks by applying image stitching binarization ...

Like Phenol (C 6 H 5 OH) and Urea {(NH 2 ) 2 C=O)}, Furfuryl alcohol (C 4 H 3 OCH 2 OH), a product of agricultural origin is capable of polymerization with Formaldehyde (H 2 C = 0) under suitable PH conditions. However, usable polymers, at least as no bake for Foundry applications are obtained only when the condensations are carried out in association with Urea, Phenol or both. The series of re...

The technique of physical modeling macro processes solidification castings on transparent models and liquids has been developed. model may be water with different salt contents. Glass bottles can used for models. Thermal insulation the top is required. developed allows to investigate effect dissolved gases microstructure castings. It shown that in have a direct process its kinetics. hot contain...

The article investigates the effect of overheating aluminum melts on mechanical properties castings. authors use data chemical analysis and study microstructure rationale for relevance topic is based a review modern scientific technical developments, as well periodicals in field metallurgical processes over past five decades. It noted that at present large amount experimental has been accumulat...

The aim of this study is the evaluation parameters core mixtures using different binder systems with regard to collapsibility cores after casting and resulting product quality castings reflecting surface requirements based on non-ferrous alloys. research compares organically bonded phenol-formaldehyde resins for production shell molding (resin coated sand), currently used in aluminum alloy Brem...
