摘要

Aluminum alloy casting is an attractive technology for fabrication of cost efficient aerospace and automotive structural components. However, casting applications for critical components for these markets are constrained by the unpredictable quality of cast products produced by existing aluminum casting technologies. Consequently most aerospace and many automotive aluminum casting applications require costly Hot Isostatic Pressing (HIP) to upgrade the quality of cast components fabricated from moderate strength aluminum casting alloys. A new casting technology, Alotech Precision Sand Casting, through rigorous capture of Ten Casting Rules and advanced molten metal treatment, quiescent molten metal flow and controlled solidification techniques, provides breakthrough metallurgical processes for fabrication of extremely sound precision castings in high strength wrought aluminum alloys. Alotech Precision Sand Castings, without HIP, have demonstrated fatigue performance equivalent or superior to wrought product. In this paper, the foundations of this advanced casting technology and results achieved to date are presented.
