Journal ArticleDOI
Classification of Bulk Metallic Glasses by Atomic Size Difference, Heat of Mixing and Period of Constituent Elements and Its Application to Characterization of the Main Alloying Element
Akira Takeuchi,Akihisa Inoue +1 more
TL;DR: In this paper, the atomic size difference, heat of mixing (H mix), and period of the constituent elements in the periodic table were classified according to the atomic sizes of the BMGs discovered to date.
Journal ArticleDOI
Recent development and application products of bulk glassy alloys
Akihisa Inoue,Akira Takeuchi +1 more
TL;DR: A review of the glass-forming ability, structure and physical, chemical, mechanical and magnetic properties of bulk glassy alloys with the emphasis on recent results obtained since 1990, together with applications of BGA, achieved mainly in Tohoku University is presented in this paper.
Journal ArticleDOI
Calculations of Mixing Enthalpy and Mismatch Entropy for Ternary Amorphous Alloys.
Akira Takeuchi,Akihisa Inoue +1 more
TL;DR: In this paper, three empirical rules for the achievement of high amorphous-forming ability (AFA) were calculated with thermodynamical functions for the gross number of 6450 alloys in 351 ternary ammorphous systems.
Journal ArticleDOI
Bulk amorphous alloys with high mechanical strength and good soft magnetic properties in Fe–TM–B (TM=IV–VIII group transition metal) system
TL;DR: In this article, a wide supercooled liquid region before crystallization was found in Fe(Co,Ni) and Fe(Zr,Nb,Ta,Mo,W)-B systems with diameters up to 6 mm.
Journal ArticleDOI
Recent Progress in Bulk Glassy Alloys
Akihisa Inoue,Akira Takeuchi +1 more
TL;DR: In this paper, a review of the formation and properties of bulk glassy alloys is presented, where the authors show that the instability of the liquid phase of metallic alloys below melting temperature is a universal phenomenon, making the formation of a crystalline phase of the bulk metallic alloy unavoidable.
