I highly recommend the textbook /"Material Science and Engineering/" by Callister and Rethwisch which you can get here https://amzn.to/4cn2v8v

Metal alloys are used in many everyday applications, from cars to coins. By alloying a metal with another element, we can control its properties and microstructure. This video covers the basic concepts of metal alloys, phase diagrams and the lever rule, to help us understand how the properties of a material are changed under different compositions.
