The investigation of high-temperature properties of metal by a method of sclerometric

Investigation of the Effect of Thermocyclic Treatment on the Mechanical Properties of Steel

“…Structural and phase transformations in the thermocyclic process are performed repeatedly at a changing "heating-cooling" temperature. The need for repeated processing at specified temperatures is due to the desire to accumulate changes in the structure of the metal, which improve the quality of products and give them properties that are unattainable with a single heat treatment [1][2][3].…”

“…When thermocyclic processing of alloys whose matrix undergoes phase transformations (ironbased alloys), significant interfacial stresses occur during repeated diffusion transformations, as well as temperature gradients between individual matrix elements, which lead to an increase in the transformation centers and, as a result, to grain grinding [8][9][10][11][12]. Alloys with a structure formed in this way have an increased impact strength, high strength and satisfactory ductility [2].…”
