铝合金低压铸造过程数值模拟
Numerical Simulation of Low Pressure Die Casting Process of Aluminum Alloy
摘要
Abstract
Aluminum alloys,characterized by their low density and high specific strength,are commonly used as lightweight materials in automobiles.Low pressure die casting facilitates smooth filling and the formation of complex,thin-walled castings,making it widely applicable in the manufacturing of typical automotive components.To optimize the low-pressure casting process,reduce casting defects,and obtain castings with superior mechanical properties,Integrated computational materials engineering(ICME)and multi-scale numerical simulation methods have been utilized to study the low pressure die casting process of aluminum alloys,which bear significant scientific and engineering value.This article provides a comprehensive review of the development of numerical simulation techniques for solidification in low pressure die casting of aluminum alloys.It concludes macro numerical simulations and their common algorithms for the filling and solidification processes,summarizes the current state of research on the microstructural evolution of primary and eutectic phases in aluminum alloys using the cellular automaton simulation,and forecasts the future development directions of numerical simulations for the solidification process in low pressure die casting of aluminum alloys.关键词
