ELINVAR ALLOY WITH HIGH MODULUS OF ELASTICITY AND ARTICLE MADE THEREFROM Russian patent published in 2016 - IPC C22C38/10 C22C30/00 C22C19/03 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, specifically, to elinvar alloys, and can be used in production of elastic-sensitive elements of precision instruments, power springs and structural components of special purpose. Age-hardening alloy with low temperature coefficient of normal elasticity modulus with high modulus of elasticity contains, wt%: cobalt - 40-45; nickel 14-17; niobium 4.5-6.5; rhenium 1.5-2.5; molybdenum 0.1-2.0; zirconium 0.5-2.5; aluminium 0.1-1.5; titanium 1.5-3.5; copper 0.1-1.5; boron 0.001-0.03; neodymium 0.001-0.05; cerium 0.01-0.1; lanthanum 0.01-0.1; iron - balance.

EFFECT: alloy is characterised by high characteristics of ultimate strength, elasticity modulus.
