![]() Similar characteristics of IHTC peak values were also observed at 30, 60, and 90 MPa applied pressures. The results showed the IHTCs initially reached a maximum peak value followed by a gradually decline to a lower level. In this work, IHTCs were determined by using the inverse algorithm based on measured temperature histories and finite-difference analysis in a five-step squeeze casting of aluminum alloy A443. However, it is difficult to determine the values of interfacial heat-transfer coefficients (IHTCs) in squeeze casting of aluminum alloys due to many influence factors. A critical portion of casting simulation is the heat transfer at the metal/mold interface. ![]() As an effective tool, simulation helps do the analysis and optimization in advance and undertake preventive action. ![]()
