This course presents the basics of understanding aluminum alloy chemistry of the alloys used in high pressure aluminum diecasting (HPDC), solidification and microstructures, the influence of impurities and subsequent melt treatment, emerging process development, melt quality analytical techniques and useful comparison with other casting processes. Hydrogen and various inclusion impurities, sources, and melt treatment----fluxing, degassing, filtration--used to remove these from the melt will be presented in Part 2 . Principles and effects of grain refinement and modification pertinent to HPDC will also be discussed.
