The material presented in this video are some highlights from NADCA’s online webinar - Alloy Effects, Phase Diagrams, Microstructure.
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. The topics that will be covered in Part 1 are: the aluminum crystallographic structure and why/how alloying is beneficial, the relevant phase diagrams for aluminum-silicon alloys which are the foundation of all aluminum foundry processes and application to HPDC, specific contributions of individual alloy elements, and understanding the microstructure of aluminum diecasting alloys.
