Using the SPH Method for Modeling the Crystallization Process of Aluminum Alloys

Abstract


 
 
 The purpose of the study was to obtain castings with increased mechanical properties by low-pressure casting using excess pressure on the crystallized casting. The simulation of the process of filling and crystallization of prototypes using the SPH method was carried out. The studies were carried out on a modernized low-pressure injection molding machine model U8261. Prototypes were obtained from AK7ch alloy, special attention is paid to interfacial interaction and intensification of the heat transfer process due to the application of excess pressure. Based on the data obtained, it was found that during crystallization under excessive pressure there is a supercooling effect that reduces the casting solidification time. The use of the SPH method for modeling foundry processes has shown a high level of reliability and requires further development.

“…The SPH method has proven to be a useful and suitable method for modeling the shape and displacement rate of complex fluid flows during casting [2,5,7,15,17,33,34,[61][62][63][64][65][67][68][69][70][71][72][73][74][75][76][77][78][79]. When discussing the application of the SPH method in casting simulation research, articles often refer to specific topics such as high pressure die casting [5,33,34,62,64,67], ingot casting [7], continuous casting [17], low pressure die casting [61], gravity casting [63,74], casting complex-shaped objects [69].…”
