Physico-technical properties formation in precipitation-hardened Fe-Ni elinvars

A study was made on the Curie point effect on the level of physical proper ties of elinvars with different character of formation of elastic modulus thermo stability, determination of the dependence of structural-sensitive elinvar prope rties on structure parameters Co, Cu, Cr, Si, Mo, w, Ti were used as the regulators of elinvar Curie point. Alloys with different titanium concentratio n after the double (dht) and mechanical heat treatment (mht) were used to obtain the different levels of interval stresses and the degree of structure heterogene ity. Alloy texture was regulated by their alloying with chromium and cobalt in combination with drawing. It is shown that the character of formation of elasti c modulus thermostability and the Curie point effect elinvar physical propertie s in a high degree. Structure heterogeneity role in separate physical propertie s regulation is assessed for alloys
