I know annealing makes a material more ductile, but what are the differences in the structuer of the material?

I have a picture I took of 1018 and 1040 untreated... if you know the difference, think you can point them out? I'm not looking for differences in any specific material I just have these pictures, just generally in any material whats different.

Can one find a book on microstructures of steel with micrographs of ferrite, pearlite, cementite and martensitic structures?
