| Abstract: | The paper studied structure and properties of a new counter-gravity casting method- vacuum counter-pressure casting aluminium alloy castings based on intelligent control by comparing vacuum counter-pressure casting with gravity casting. The result indicated that condition of crystal nucleus and solidification feeding of vacuum counter-pressure casting based on intelligent control was very good, thus grains of castings was fine, and structure was dense and uniform, meanwhile, its mechanical properties were improved greatly. |
| Keywords: | Vacuum counter-pressure casting Aluminium alloy castings Structure Property |
