Recent Advances in Numerical Simulation of Solidification Process in Cast Magnesium Alloys
Magnesium alloys are widely used in automotive and aerospace fields due to its lightweight,high specific strength,good damping performance,etc.Numerical simulation can be used to control microstructures,reduce casting defects,improve mechanical properties,and optimize casting process parameters by reproducing various macro and micro physical processes during the casting process.In this paper,the current research situations of numerical simulations of dendritic and eutectic microstructures,the casting defects of segregation,gas hole,hot tearing and so on,and mechanical property prediction have been reviewed,and the research progress in the numerical simulation aspect of the forming process simulation of cast magnesium alloy for last two years is further briefly introduced.Finally,the existing problems and the future directions of the present researches are suggested.
