Abstract

Dissolving in iron, the alloy elements influence the range of austenite and ferrite. In point of influence they have over the allotropic transformation of iron, the alloy elements in the chemical composition of steel type 15VMoCrl4X split into two large groups: gamma forming elements (nickel, manganese, carbon, nitrogen etc.) and alpha forming elements (chromium, molybdenum, vanadium, silicon, aluminum). The alloy elements increase the tensile strength, but differently: Cr, Mo and V increase the resistance of ferrite less than Si, Mn and Ni. The Si, Mn and Mo decrease the resilience of ferrite, more than Ni and Cr do. In this paper we suggest a mathematical shaping of the influence of the main alloy elements over the resistance characteristics of steel type 15VMoCrl4X. It has been noticed that the alloy elements increase the tensile strength, but differently: Cr, Mo and V increase the resistance of ferrite less than Si. Mn and Ni. The Si, Mn and Mo decrease the resilience of ferrite, more than Ni and Cr do. The increase of the alloy content over 1.2% leads to a sudden fall of the resilience. The exception of this rule is nickel that both increases the resilience of ferrite and decreases the transition temperature.
