Description	The research of phase equilibria in Mn-Nb and Mn-Ta system has been conducted. In our study, a stable Laves phase was confirmed in both systems, but no other phase was detected experimentally. Melting and transformation temperatures of alloys in both systems were determined by DTA experiments, and this information was supported by phase analysis via scanning electron microscope (SEM) with wavelength dispersive X-ray (WDX) and energy-dispersive X-ray (EDX) analyses. Results of these experiments supported by ab initio calculations and calorimetric measurements of the energy of formation of Laves phases enable us to determine the phase diagrams of both systems by the CALPHAD method.
