Can someone explain me the possible reasons why after homogenization of an austenitic steel, I obtain smaller hardness (about 100HV smaller) but the same yield strength? For me it's not logical... Lower hardness is probably conencted with recrystallization and grain growth, but shouldn't it be...
Hello everyone!
I have a question:
I am currently working on an austenitic steel and after applying Hall-Petch law, the slop of a curve (on HV vs d^-1/2 graph) is different than taken from the literature... How can I explain this? May it be connected with "k" coefficient?
Another question...
