How to use phase diagrams and the lever rule to understand metal alloys

Interested in learning more?
📚I highly recommend the textbook "Material Science and Engineering" by Callister and Rethwisch which you can get here amzn.to/4cn2v8v

Metal alloys are used in many everyday applications ranging from cars to coins. By alloying a metal with another element we can control it's properties and microstructure. This video covers the basic concepts in metal alloys, phase diagrams and the lever rule, to help us understand how a materials properties are changed with varying compositions.
