HI all
I have some questions regarding the micro structure of 4140 steel. It is widely used in the drilling equipment. Is it possible that prioir austenite grain boundaries can be present in quenched tempered conditions or is it possible to reveal the prior austenite grain boundries using 2% Nital?
1 more question presence of prior austenite grain boundaries are desirable or are dangerous to the integrity of the material.
Thanks
