Progress in Integrated Die Casting of Aluminum Alloys
Aluminum alloys,known for their low density and high specific strength,are widely used in aerospace and automotive lightweight applications.Integrated die casting enables the production of large,complex,thin-walled castings,effectively aiding in weight reduction and range extension for aircraft and automobiles.This paper provides a comprehensive review of the development of large integrated die casting for aluminum alloys.It analyzes the compositional design of non-heat-treatment aluminum alloys and highlights the characteristics of the developed alloys.Additionally,it introduces the progress of domestic and international development of large integrated die casting machines and molds.The current state of numerical simulation research is summarized regarding mold filling,solidification,defects prediction,microstructure,thermal stress,and fatigue life prediction of integrated die casting parts.The paper concludes with a discussion of future developments in integrated die casting technology.
