I am facing problem as only one or two peaking are coming while performing XRD on Fusion Zone of 316L SS and alloy 800. I want to know where i am committing mistake.I have attached the XRD image.
You are not making mistake, because of the coarse grains in the fusion zone and solidification texture you are getting only those peaks. IF you haven't spin the sample during measurement it may help a little but I would not expect too much.
we know that XRD analysis is a powerful method for phase analysis on powder samples. Would you tell me about your sample preparation method in your analysis ?
