ALLOY WITH GLASS-FORMING PROPERTIES AND METAL MATERIAL WITH COAT MADE FROM SAID ALLOY

摘要

FIELD: metallurgy.;SUBSTANCE: proposed alloy with glass-forming property made up of at least one element from every group of elements A with atomic radius smaller than 0.145 nm, from group of elements B with atomic radius varying from 0.145 nm to less than 0.17 nm, and from group of elements C with atomic radius 0.17 nm. Total content of elements from group of elements A makes 20-85 at %, that of elements of group of elements B makes 10-79.7 at %, and that of group of elements C varies from 0.3 at % to 15 at %. Fraction of element a from group of elements A makes 70 at %, that of element b of group of elements B makes 170 at %, and that of element c of group of elements C makes 70 at %, or more, where elements a, b, c are elements with maximum content of elements A, B, C, while enthalpy of fluid formation between two any elements selected from a, b, c is negative. In the case of coat, amorphous phase occupies volume fraction of 5%, or more. Surface layer of said coat may consist of mono phase of amorphous phase.;EFFECT: higher antirust and heat reflection properties.;36 cl, 7 dwg, 8 tbl, 8 ex
