Le-bail fit of the room temperature indexed XRD patterns of (a) Fe2CrAl (b) Fe1.75Mn0.25CrAl (c) Fe1.5Mn0.5CrAl (d) Fe1.25Mn0.75CrAl and (e) FeMnCrAl. Inset of (b) shows the shifting of peak with increasing Mn substitution along with decrease in intensity of (200) peak for selected compositions of Fe2CrAl, Fe1.5Mn0.5CrAl and FeMnCrAl. Inset of (c) depicts the change in intensity ratio of I200/I220 reflection lines with Mn substitution.
