a, b In situ neutron-scattering patterns of Alloys 1 (Al20Cr5Fe50Mn20Ti5) and 7 (Al30Cr5Fe50Mn10Ti5) at elevated temperatures, respectively. The label of order means that the reflections are exclusive to the L21 structure, while the label of fundamental means that the reflections are common to both the ordered L21 and disordered BCC structures. c, d The MC-calculated LRO parameters as a function of temperature in Alloys 1 and 7, respectively. e, f The MC-calculated SRO parameters as a function of temperature in Alloys 1 and 7, respectively. The black arrows indicate the change of the most abundant, Fe, as the neighbor of all elements.
