Determination of Austenite Decomposition Temperatures Using Thermodynamic Sw Factsage

Abstract

The article will deal with the determination of austenite decomposition temperatures using the available SW FactSage. The determination of austenite decomposition temperatures is one of the basic information that can provide the technologist and subsequently help to change the properties of steel during steel processing. Austenite is one of the interstitial carbon solutions. Austenite is characterized by a cubic area-centered lattice and its structure is formed by regular grains. Various phases or structural components may form during cooling of austenite. Depending on the cooling of the steel, perlite, bainite and martensite may be formed. During the cooling of the steel, the area-centered lattice changes to a spatially centered iron lattice alfa. The aim of the presented work will be to determine the decomposition temperatures of austenite in 41Cr4 steel.
