Study of MnSb alloy on the range of 43% to 50% of at.%Sb, revealed an unexpected presence of MN2SB phase

摘要

The manganese-antimony (MnSb) alloys with specific stoichiometry, on atomic range from 43% to 50%at.Sb, as cast (with no quenching or annealing), were analyzed using OM, VSM, DSC and XRD characterization methods. The XRD diffractograms were refined using Rietveld method, were possible to identify four different phases: a) Mn1, 09Sb (hexagonal, spatial group P63mmc); a’) MnxSb (1.092
