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:
There is a well known law for metals, connecting hardness and yield strength:
H = α x YS
α for metals should be around 3... But it's not working once again in my case - it's about 1,2. How can I explain this?
I would be grateful for any indications!
