Super-high strength of over 4000 MPa for Fe-based bulk glassy alloys in [(Fe1-xCox)0.75B0.2Si0.05]96Nb4 system
TL;DR: In this article, high-strength Fe-based bulk glassy alloys with super-high fracture strength of over 4000 MPa and high glass-forming ability were synthesized by the copper mold casting method.
Journal ArticleDOI
Fe- and Co-based bulk glassy alloys with ultrahigh strength of over 4000 MPa
TL;DR: In this paper, the fracture strength has a good linear relation with Young's modulus, glass transition temperature or liquidus temperature and it is concluded that the origin for the ultrahigh strength is attributed to the strong bonding nature among the constituent elements.
Journal ArticleDOI
Superhigh strength and good soft-magnetic properties of (Fe,Co)–B–Si–Nb bulk glassy alloys with high glass-forming ability
TL;DR: In this article, the substitution of Co for Fe caused an increase of glass-forming ability as well as an improvement of mechanical and magnetic properties, and the bulk glassy alloys exhibited superhigh fracture strength of 3900-4250MPa, Young's modulus of 190-210GPa, elastic strain of 0.02, and plastic strain of0.0025.
Journal ArticleDOI
Composition design of high B-s Fe-based amorphous alloys with good amorphous-forming ability
TL;DR: In this article, the composition design rules for high B s amorphous alloys are introduced from the binary phase diagram, atomic size and the effects of amorphizing forming elements on magnetic performance and ribbon manufacturability.
