Interested in learning more? 📚I highly recommend the textbook "Material Science and Engineering" by Callister and Rethwisch which you can get here The way we process metals strongly influences their mechanical properties. In this video we cover how we can use approaches such as alloying, strain hardening and precipitation hardening to strengthen a metal by modifying it's microstructure. 00:00 Introduction 00:18 Why is this important? 01:33 How can we strengthen a material? 02:04 Solid solution hardening 03:15 Grain size effects 04:47 Strain hardening 05:50 Precipitation hardening 06:40 Solution heat treatment 07:34 Precipitation heat treatment 08:32 Overaging 09:11 Different forms of low alloy steel 10:31 Non-equilibrium phases and structures of steel 11:36 Time-temperature-transformation plots (TTT diagrams) 13:20 Summary This is a follow up video to a previous one on "How to use phase diagrams and the lever rule to understand metal alloys". and "How to select the right steel by understanding equilibrium phase diagrams". #Alloying #StrainHardening #HeatTreatment Twitter: Personal website: Personal website: About us:
