TALAT Lecture 1203: Phase Diagrams

This lecture aims at developing a qualitative understanding of binary phase diagrams by reference to the model systems Cu-Ni, Ni-Pt, Au-Ni and Ag-Cu, and also by reference to the Phase Rule. It applies the basic concepts of phase diagrams to binary aluminium alloys; it also aims at extending the discussion to an outline of ternary phase diagrams, and at showing how a so-called pseudo-binary section can be applied with benefit to the Al-Mg-Si system for alloys balanced in Mg₂Si
