MSE 201 S21 Lecture 39 - Module 4 - Precipitation Hardening, Revisited

[@JustinSmith-ug9wm]

Very good explanation!

[@layaoworu7517]

Why is there a dip in the Zones part of the Graph? I understand the overaging dip but why should the hardness go down during the zones phase? Can somebody please explain?

[@grairiaamina6275]

Thanks

Does not explain the why things happen as they do and is also confusing in the presentation order. There still a lot of room for improvement
