| Abstract: | The Semi-Solid Al-7%Si Alloy produced by method of mechanical stirring was reheated by electrical resistance furnace and formed.The microstructural evolution was investigated.Heaing with electrical resistance furnace ,the ring flange part was successfully produced by method of semi-solid die forging and liquid die forging.The choice of the parameter on the stirring process and liquid die foring(semi-solid die forging) was also discussed. |
