    The present work provides an effect of the carbon content on the potency of the intragranular ferrite (IGF) formation for each inclusion size. Moreover, the critical diameters of the TiN, TiO and VN inclusions for IGF formation were calculated, as shown in this figure. The calculated critical diameter was also found to be decreased with the increase of carbon content.

    The isothermal oxidation of the indefinite chill (IC) roll (shown in Figure 1) is investigated by using a thermogravimetric analyzer. Results show that the oxidation kinetics follow a linear trend, and the oxide scale consists of two layers after the oxidation in dry air but three layers in humid air above 600 °C. The water vapor accelerated the oxidation of the matrix and the graphite.

  3. Effect of the Cold Rolling Reduction on the Microstructural Characteristics and Mechanical Behavior of a 0.06%C–17%Mn TRIP/TWIP Steel

    A 17%Mn-0.06%C steel was studied after 45% and 90% cold rolling and subsequent annealing at 700 °C for different times. Mechanical properties such as yield and tensile strength, total elongation and strain hardening were determined and correlated to microstructural characteristics, while also texture evolution in austenite and α′- and ϵ-martensite was described..

    Herein, we have investigated the thermophysical properties and solidification defects of Fe–Mn–C TWIP steels. The low solidification temperatures, weak heat conduction property, and high thermal expansion coefficient of austenite TWIP steel have been experimentally revealed by comparing with low carbon steel and stainless steels. The shrinkage porosity and segregation characteristics of high alloy TWIP steel have also been described.

    A new sulfide capacity model based on corrected optical basicity has been developed in the present paper for basic Al2O3 containing slags. A mean deviation of 3.23% is achieved for the present model in basic Al2O3 containing slags and this value is obviously lower than that of other models. The applicable range of the present model is given.
