Dear Mr Bhowmik, do not expect a massive metal ingot to be necessarily free of preferred orientation, in particular in presence of a dendritic microstucture. Thus it should be no surprise to observe wrong reflection intensities. Or did you manage to make a "powder" from your Cr based material?

Hello, I am studying a refractory metal Laves phase (Cr-Cr2X-based) system. My alloys arc arc melted an annealed. Hence it has a typical dendritic microstructure. The two phases in the material are Cr-rich and the intermetallic Cr2X. The Cr phase has a bcc and the intermetallic has a complex C1
