NICKEL-BASE AMORPHOUS ALLOY Russian patent published in 2003 - IPC

FIELD: metallurgy. SUBSTANCE: invention relates to amorphous precision nickel-base alloys. Invention proposes amorphous nickel- base alloy containing molybdenum, silicon and boron and it contains additionally chrome and cerium in the following ratio of components, wt.-%: chrome, 10.0-20.0; molybdenum, 25.0-40.0; silicon, 6.0-7.5; boron, 4.0-5.0; cerium, 0.8-1.5; nickel, the balance. Ratio of total content of chrome and molybdenum to content of nickel must be in limits: 0.6 2.4, ratio of content of silicon to content of boron must be in limits Si: B = 1.4-1.7 and total content of silicon and boron must be in limits Si + B = 10.0-12.0 wt.-%. Invention provides the enhancement of strain sensitivity in retained strength properties. Proposed alloy can be used for making high-strength ribbons, fibers and microwires with high coefficient of strain sensitivity. EFFECT: improved and valuable properties of alloy. 4 cl, 1 tbl
