The phase diagrams of neodymium-aluminum binary systems have been studied extensively during the last three decades. Most common methods of preparation of Nd-Al alloy is by melting the component species according to the desired ratios followed by homogenization. However, these alloys can be prepared by other methods such as aluminothermic reduction of neodymium oxide or fused salt electrowinning. In the present work aluminothermic reduction of neodymium oxide with excess of aluminum was used to make the alloys. The melted alloys were characterized with the help of optical microscope, Electron Probe Micro Analyzer (EPMA) and by X-ray Diffractometer (XRD). Based on the results obtained, few modifications pertaining to aluminum rich side of neodymium-aluminum phase diagram are suggested.
