In this work investigation of phase(s) obtained in just melted alloy using x-ray diffraction XRD patterns was done. Many research articles suggested melting method to prepare Nitinol alloy in vacuum induction furnace, or vacuum arc furnace supported with stirring device, to prevent contaminants and oxidation. But because of its expense, four experimented method were utilized. First one is under cover in atmospheric pressure. Second method just like the first but at higher temperature. The third was done using evacuated capsules and the fourth was done using vacuum plasma spraying system with modulation. X-ray diffraction shows different phases according to procedure type.
