Aluminium properties

[Yukawa]

Hi! I am very new in the material science!

I need to find a relations between grain size an yield stress for aluminum alloys. And what about micro-hardness can I connect it with some macro properties of aluminum alloys?

Hi Yukawa

to the Surface Engineering Forum.

Generally decreasing grain size increases yield stress. The Hall-Petch equation:

   

where

?0 is the stress required to move dislocations,
k is a material constant, and
d is the grain size.

Hardness will also have a relationship with grain size and yield stress.

Thank you! I know for that formula! But I need more. Can you recommend me some papers, or books?

Hi Yukawa

Failing input from other members, I can only suggest doing more advanced searches in Google and the like
