Abstract

Modern requirements and approaches to getting new alloys with increased strength and physical characteristics as well as their applicationshave been considered. Basic principles of composition developing of invar alloys with high mechanical properties at temperature coefficient low values of linear expansion have been presented. Chemical compositions influence on reaching the spread range of multi-purpose alloys operational properties on the example of iron-nickel compositions has been analyzed. Research results of the influence of alloying elements on corrosion resistance of high-strength invaralloys are provided.

Keywords

Multifunctional alloys, invars, durability, thermal straining hardening, temperature coefficient of linear expansion.
