Analysis of non-metallic inclusions in AZ91 alloy casts with process foundry return in high-pressure die castingAbstract
The article presents research results of the process foundry return influence in the AZ91 alloy charge on the change in the structure of castings made by the high-pressure casting method, with special consideration of the formation of non-metallic inclusions. Based on the observations of inclusions by the scanning microscopy method, the chemical composition of the inclusions in melts with different process scrap contents in the charge was determined.
