a–b, d–e The morphology of the as-cast S-4 alloy confirmed by electro-probe microanalyzer (EPMA) in TD (transverse direction)-ND (normal direction) plane (a) and LD (loading direction)-TD plane (b), respectively. (d) and (e) are enlarged regions in (a) and (b) marked with a red box. c Electron back-scattered diffraction (EBSD) inverse pole figure of crystal orientation for S-4 inside the TD-ND plane. f–g Element mappings of Ho (f) and Fe (g). h Pole figures by neutron diffraction texture analysis for the bulk orientations of (004)H, (600)H, (110)α, and (002)α directions.
