The medium-Mn steel possesses ultrafine-grained (UFG) duplex microstructure consisting of ferrite and a large amount of metastable austenite. The metastable austenite in UFG duplex microstructure is obtained by austenite reversion during intercritical annealing. The study of austenite reversion kinetics is of great importance for the heat treatment...

MA956, a commercial ferritic grade of Oxide-Dispersion-Strengthened (ODS) steel, was investigated using transmission electron microscopy (TEM) to evaluate the influence of high-temperature thermal cycles on the nanometric dispersed oxides. Analyses of the oxide size distribution were carried out on foils from the as-received MA956 and following tre...

Oil&gas producing industry today is increased production volumes from old deposits on land, offshore and deep-water. The materials used to create modern equipment that meets these trends should be distinguished by increased productivity in conditions of corrosion and high pressure, to ensure trouble-free operation. In such conditions, taking into a...

The main goal of this paper is mathematical modelling and computer simulation of isothermal decomposition of austenite in steel. Mathematical modelling and computer simulation of isothermal decomposition of austenite nowadays is becoming an indispensable tool for the prediction of isothermal heat treatment results of steel. Besides that, the predic...

A homogeneous microstructure is required for consistent mechanical properties in normalised Nb-Ti-V microalloyed plate steels. Frequently, as-hot rolled microalloyed plate steels have a banded microstructure that is persistent even after normalising heat treatment (NHT), and this leads to inconsistencies and some scatter in mechanical properties. T...

We studied the influence of temperature and soaking time on rod billets made of steel 50. The development of the decarburized layer after induction heating and soaking in the resistance furnace was taken into account. When analyzing cooled down rod billets subjected to heat treatment, a continuous and stable development of a ferritic layer on the e...
