How to measure grain size of tempered martensite
(OP)
I want to measure grain size of tempered martensite which has ferrite also as observed in microstructure as per ASTM 112.If it is possible.Then how.

And yes, it may be possible to determine the grain size of a heat treated and tempered part depending upon what it is and how it was heat treated and prepared.

Revealing the prior austenite GS with a picral really is an art. I have tried many different concoctions with varying levels of success over the decades. One thing I have learned is that old, nearly black etchant often works better than a fresh solution.
