Abstract

The study aimed to determine the solidification and cooling parameters of a low-alloy manganese steel AISI 1552 (55Г) in a sand mold. The finite element method was used to characterize the temperature distribution and the evolution of the solid fraction during solidification. After casting and machining, the parts were examined by liquid penetrant testing, which revealed cracking throughout the entire body of the parts as well as the presence of porosity. The numerical simulation showed that the temperature distribution remains practically constant between 1.49 and 3.96 seconds, and that after 36 seconds, when the temperature reaches 1164 °C, a thermal decrease begins from the feeding channel toward the thinner zones. Solidification was completed approximately six hours after the onset of cooling. These results make it possible to relate the thermal conditions of the process to the appearance of defects, particularly cracks and porosity, in the cast parts.
