Translated title of the contribution: IMPACT OF CARBON ON THE STRUCTURE AND THERMAL PROPERTIES OF NEW CARBON SUPERINVAR ALLOYS

Research output: Contribution to journalArticle

Abstract

Super-invar alloys based on Fe-Ni-Co with additions of carbon in wide range (0,6 %, 0,8 % and 1,7 % С) have been investigated. Metallography analysis showed that graphite phase distributed throughout the volume of alloy in a fine state. Moreover, the size of graphite inclusions rises with the increasing of the total contents of carbon. It is showed, that after a heat treatment the morphology of graphite phases may change. Thermal analysis revealed that it is necessary to up the temperature of annealing unto 800 °С because at that temperature the graphitization processes proceeds more fully. It is also showed that after annealing (800 °С, 3 h) investigated alloys induce minimal thermal expansion (α 20-100 < 1,5·10 -6К -1).
