Ni-based amorphous alloy with high ductility, high corrosion resistance and excellent delayed fracture resistance

摘要

[Problem] To prepare an amorphous alloy as an authentic industrial-use material with a wide range of applications by solving various problems such as delayed fracture and ductility. [Solution] The alloy includes 63 at% or more of Ni and consists only of, as a semimetal for amorphization, other than P. The semimetal may include, for example, 10 to 25 at% of B and one or more of Cr, Mo, and Nb as remaining main elements.
