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

[@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?

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
