The effect of overheating of aluminum melts on the mechanical properties of castings

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 accumulated, which indicates metal are complex dynamic systems. A significant structural state initial melt formation structure ingots obtained from this established. In work, heat treatment was studied high-strength cast aluminum-magnesium alloy with wide crystallization range (433 K). order to obtain dense castings, pouring carried out bottomless mold slotted gating-feeding system, installed surface copper water-cooled box. This provided directional solidification alloy. Experimental results presented, processed, castings studied.
