Abstract
Materials on the base of multifunctional alloys with the special physical and mechanical properties for developing the equipment of new generation are in high demand at present. Among these materials are Invar alloys with the minimum thermal expansion and the increased level of mechanical properties, in particular, strength ((c) hardness (HV). Such materials are necessary for creating the components of navigation systems (accelerometers, gyroscopes), sensors of small displacements, laser technology (adjustment units, mirror), antennas, waveguides, etc. The results of complex research of innovative high-strength multifunctional invar class alloys are presented. The effect of thermal treatment on the formation of structure and physical and mechanical properties of alloys in terms of iron nickel alloys, carbon, cobalt and vanadium is shown. Relating to the conditions of OJSC Motovilikhinskiye zavody the base industrial technology of the production of the nano-structured billets of the multifunctional alloys of new generation has been developed. This technology ensures to achieve the increased level of mechanical strength (σв1100 MPa) and anomalously low values of the thermal linear expansion coefficient (1∙10-6К-1).
