Why is it important?
Comparison of all dilatograms made it possible to formulate a conclusion about the discrete effect of the temperature and time of annealing of cast samples on the temperature range of the practically used invarity of the alloy.
Perspectives
The nature of the selected effects is associated with the presence of carbon atoms in the solid solution due to the hybridization of the electron orbitals of these atoms during heat treatment alloy, which change the invarness and graphitization temperatures of the structure.
