This antique text contains a comprehensive reference book on the subject of the metallography of aluminum alloys. This text was intended for consultation by the plant metallurgist, rather than as a textbook for students, and the chapters of this book include: Equilibrium Diagrams, Binary Diagrams, Ternary Diagrams, Quaternary Diagrams, Polishing and Etching, Macro-Examination, Polishing, Etching, Constituents, Master Allows, Aluminium-Copper Alloys, Aluminium-Silicon Alloys, and much more. Many antique books such as this are increasingly costly and hard to come by, and it is with this in mind that we are proud to republish this text here.
