| 摘 要： | As a special casting process, counter-gravity casting has many advantages especially in producing thin-wall complicated castings and has widely been used in industry 1]. In recent ten years, various different counter-gravity casting processes have been continuously developed such as vacuum suction casting, low-pressure casting and counter-pressure casting 2-4] et al. Vacuum counter- pressure casting is a new kind of counter-gravity casting technology that was developed in recent years. It ha…

| Abstract: | The microstructure and properties of vacuum counter-pressure cast aluminum alloy were studied. Results indicated that under the condition of vacuum counter-pressure, liquid melts fill mould cavity under the vacuum and crystallize under high pressure which have very good effect on nucleation and solidification feeding. Compared with gravity casting, the microstructure of vacuum counter-pressure cast aluminum alloy is much finer and more uniformly distributed. Mechanical properties of vacuum counter-pressure cast aluminum alloy are improved significantly. |
