Abstract

The application of numerical simulation of rheological forming of alloy can effectively predict the filling and solidification process in semi-solid forming

analyze the pressure field

velocity field

solid phase distribution

filling speed

filling temperature and defects in forming process

and provide relevant decision help for the related schemes optimization of process and design. The theoretical basis of numerical simulation were reviewed of rheological forming in recent years as well as the research progress and future development direction of rheological forming alloys at home and abroad.
