Hello everyone,
I have a question about bands and islands found in grains of AISI 1045 steel after heat treatment of:
Austenization (inert atmosphere): At 880 C for 1 hour
Annealing: At 550 C for 1 hour
The chemical composition is: C: 0.45 %wt
Mn: 0.3-0.6 %wt
S: <0.03 %wt
Cr+Ni+Mo: < 0.6 %wt
Si: <0.4 %wt
In this micrograph,
The dark bands (waves) in red box and again dark relatively straight lines in blue boxes.
In this micrograph:
The white islands in grain with red box.
I couldn't figure out what they could be, so I'm asking for your help. If you can give some head-up, I'd appreciate a lot.
Thanks in advance
