Early in his career, Dr. Hono pioneered atom probe field ion microscopy (APFIM) and later three-dimensional atom probe (3DAP) characterization of metallic nanostructures to elucidate structure-property relationships of various alloys with potential industrial applications. He also contributed to the early development of laser-assisted 3D atom probe and demonstrated successful 3DAP analysis of insulator materials using UV lasers. His atomistic characterizations of solute clusters and GP zones in aluminum alloys were pioneering at the time for the study of precipitation sequences at the atomic scale. Extending this research to magnesium alloys, his group developed high-strength heat treatable wrought magnesium alloys with excellent formability. He also pioneered the atomistic characterization of amorphous alloys and their crystallization processes, and the research that elucidated the crystallization mechanism of the amorphous Fe-Si-B-Nb-Cu alloy served as a guiding principle for the subsequent development of nanocrystalline soft magnetic materials. In recent years, he has vigorously pursued the multi-scale analysis of the microstructure of rare-earth permanent magnets through the complementary use of SEM/TEM/3DAP, and established a coercivity mechanism that overturns the conventional view. Based on this, Dr. Hono's group developed a grain boundary infiltration method using eutectic alloys that dramatically improves the coercivity of neodymium magnets without using Dy. In addition, systematic TEM studies of the nanostructures of FePt thin films led to the development of FePt-C nanogranular perpendicular thin films, which proved to be the prototype of industrialized FePt-X heat-assisted magnetic recording (HAMR) media. His group has also made remarkable achievements in the search for half-metallic Heusler alloys and unprecedented high magnetoresistive performance has been demonstrated in CPP-GMR devices by atomic control of the Heusler FM/NM interfaces, which have attracted interest as potential magnetic sensor applications.
