Current Topic:
Induction hardening
sir,
I have read in a book that due to very high rate of heating in induction hardening the hardening range is shifted on the upper side, that is in case of induction hardening the temperature required for hardening is greater than in case of conventional hardening in a furnace.
secondly, more dispersed the initialmicrostructure os a steel the less time it takes to change into Austinite and moreover the dispersed structure lowers the transformation temperatures
Would you like to explain me the reason and the mechanisim behind it?
OR
If iam mistaken in understanding the facts,  would be obliged if you could clear my doubts.

regards

lakhtin...
