Hi all
I am learning about Grain Size Hardening, and find it difficult to understand some concepts.
With refer to the link:
http://aluminium.matter.org.uk/conte...eid=1000301064
What is that dislocation source, and why it emits dislocation when the stress is increasing?
For my understanding, dislocation are some imperfections already exist in the metals,so I find it very strange to have something called "source" to continuousy produce some dislocations. Can anyone help answer what's S1 and S2 and why's that? Please.
