Alloy Design Based on Computational Thermodynamics and Multi-objective Optimization: The Case of Medium-Mn Steels
(2017)A new alloy design methodology is presented for the identification of alloy compositions, which exhibit process windows (PWs) satisfying specific design objectives and optimized for overall performance. The methodology is ... -
Effect of austenite stability on fatigue performance of TRIP 700 steel
(2013)The role of austenite stability on fatigue performance of low-alloy TRIP steel 700 has been experimentally investigated. Heat treatment process was used to produce varying microstructures, characterized by different initial ... -
Effect of retained austenite stability on cyclic deformation behavior of low-alloy transformation-induced plasticity steels
(2019)The retained austenite (RA) characteristics of Al-containing TRIP700 steels have been manipulated using varying bainitic isothermal transformation (BIT) processing. The microstructural evolution was investigated using ... -
Fatigue behavior and retained austenite transformation of Al-containing TRIP steels
(2016)In material selection for the design of advanced lightweight automotive steel components, fatigue performance is of particular significance. High strength TRIP steels offer very good cyclic behavior, especially under cyclic ... -
Kinetics of strain-induced transformation of dispersed austenite in low-alloy TRIP steels
(2014)A model describing the kinetics of the evolution of martensite volume fraction during the strain-induced transformation of dispersed austenite in low-alloy TRIP steels has been developed. The model is based on the modification ... -
A method for the calculation of retained austenite evolution during heat-treatment of low-alloy TRIP-assisted steels
(2006)Despite the critical effect of heat-treatment, and in particular of the isothermal bainitic treatment stage, on the amount and stability of retained austenite in the microstructure of low-alloy TRIP-assisted steels, ... -
Multi-phase field modeling in TRIP steels: Distributed vs. average stability and strain-induced transformation of retained austenite
(2022)Austenite stability and dispersion are key parameters controlling the strain-induced transformation of Retained Austenite (RA) to martensite in TRIP steels. Stabilization is achieved through a two-stage heat-treatment ...
