- The primary scientific achievement of professor A. Inoue is the pioneering development and application of bulk metallic glasses (BMGs)
(1988-present).The first synthesis of BMGs by copper mold casting was made for lantanide(Ln)-based multicomponent alloys in 1990, followed by the formations of Mg- and Zr-based BMGs before 1993. Based on these novel data, A. Inoue proposed the three component rules for the stabilization of supercooled liquid region and the formation of BMGs (later named after him). By applying these rules, A Inoue et al. succeeded in developing more than 500 types of BMG, including with diameters of above 10 mm, from alloys based on Ln, Mg, Zr, Ti, Fe, Co, Ni, Cu, Pd and Pt. Various casting techniques were proposed for the production of BMGs.
- It is noteworthy that in 1995 A. Inoue et al. for the first time synthesized Fe-based BMGs, which resulted in their subsequent vast applications as soft magnetic and structural materials. Subsequently, A. Inoue et al. demonstrated that these materials exhibit unique properties, such as high elastic strain, high strength, high fracture toughness, high fatigue strength, high corrosion resistance, good plasticity, ability to significantly become deformed within the range of overcooled liquid existence, as well as good soft magnetic properties. Thanks to the high glass-forming ability and unique functional characteristics, BMGs are extensively used in motors, reducers, springs, casing, hinge, watch parts, transformer cores, magnetic sensors and shields, sporting goods, ornaments and surface coating for other materials. These alloys were protected by such trademarks, as Vintage, GALOA, Amobeads, Liqualloy and SENNTIX.
- The high plasticity of cementite in plain carbon and complex steels was explained for the first time (1978).
- Fe- and Co-based amorphous alloys were synthesized for the first time in the form of wire with a circular cross section having unique soft magnetic properties, followed by their successful application as the trademark of SENCY
- Stable icosahedral alloys (such as Al65Cu20Fe15) were detected, and their fundamental properties were examined (1987).
- High-strength Al-based amorphous and nanocrystalline alloys were developed and later commercialized as ultra-high specific strength materials under the trademark of GIGAS
- Nanocrystalline Fe-based soft magnetic alloys in Fe-Zr-Nb-B-Cu system were developed, and their applications to soft magnetic materials with high saturation magnetic flux density materials above 1.8 T (Trademark; NANOPERM) was substantiated
- Equiatomic (high-entropy) BMGs were developed for the first time (2002).
- Ductile icosahedral-based alloys were developed (2020).
