Hi every body
I have an elementary question because i am confusing now.
I should prepare different mixtures of powders for sintering. the instruction gave me the fraction of element in mass percent but i want to have one of the compund in the mixture in Vol%. let me to write one of the mixture...
I have two samples that have been produced by extrusion(from powder). K190(X220CrVMO 13-4) and a steel that is H13.
I am looking for Proper etchant solution to see the carbides and also i want to reveal the matrix if it is Austenite or martensite?
Thanks for any kind of help.
