I need make a quantification of alpha prime martensite phase in hyper duplex stainless steel deformed at subzero temperatures. This specimens was analized by XRD.
This phase is BCC, you can use alpha iron or ferrite card, most probably you won't be able to differentiate it from ferrite so for quantitative measurement you will need undeformed sample, the martensite content will be the difference between ferrite content in deformed and undeformed sample.
