In the proposed study, various Mn1-xBix compositions in the vicinity of the MnBi stoichiometry will be synthesized through argon arc-melting and subjected to melt-spinning at conditions assuring an amorphous state of the products. Crystallization of the melt-spun alloys into the MnBi LTP structure will then be systematically studied for different heating rates, temperatures, exposure times and external magnetic fields. Characterization of the phases, microstructure and magnetic properties will allow for a better understanding of the practical aspects of the MnBi LTP metallurgy. The completed study is expected to provide a new manufacturing method for anisotropic highly pure MnBi alloy suitable for development of improved MnBi permanent magnets.
