ALLOYS HAVING HIGH AMORPHOUS FORMABILITY AND ALLOY-PLATED METAL MEMBERS MADE BY USING THE SAME

摘要

An alloy with a high glass forming ability characterized by containing a group of elements A with atomic radii of less than 0.145 nm of a total of 20 to 85 atm%, a group of elements B with atomic radii of 0.145 nm to less than 0.17 nm of a total of 10 to 79.7 atm%, and a group of elements C with atomic radii of 0.17 nm or more of a total of 0.3 to 15 atm%; when the elements with the greatest contents in the group of elements A, group of elements B, and group of elements C are respectively designated as the "element a ", "element b ", and "element c ", by the ratio of the content of the element a in the group of elements A (for example, Zn and/or Al), the ratio of the content of the element b in the group of elements B (for example, Mg), and the ratio of the content of the element c in the group of elements C (for example, Ca) all being 70 atm% or more; and by the liquid forming enthalpy between any two elements selected from the element a, element b , and element c being negative.
