The design and development of new multiphase microstructures for specific technological applications require not only a characterization of the final microstructure, but also a detailed knowledge at the level of individual grains of the phase transformations taking place during the material processing. The availability of intense high-energy X-ray beams (50 to 300 keV) at a number of synchrotro...

This work investigates the effect of a constant load on hydrogen diffusion through transformation induced plasticity (TRIP)-assisted and quenching partitioning (Q&P) steel containing metastable retained austenite by combining electrochemical permeation thermal desorption spectroscopy. Furthermore, comparison is made with ferrite/martensite dual phase (DP) steel, which serves as reference materi...

TRIP-assisted CMnSiAl steels with a fully martensitic initial microstructure have been studied in order to investigate the effect of partial substitution Si by Al. The steel was fabricated casting sand mold, hot forged, homogenizing, rolling, cold intercritical annealing, and finally, an isothermal bainitic treatment. During annealing at 1023 K (750 °C) for 420 s, matrix consisting 50% proeutec...

The stress-induced transformation behavior of retained austenite is considered in this work. With the development of transformationinduced plasticity (TRIP) steels this deformation mode is of growing importance. Twinned martensite structures were calculated using the crystallographic theory of martensite. An available work criterion was used to predict the transformation potentials for 16 diffe...

This manuscript aims to present an overview of quenching and partitioning (Q&P) heat treatment usually applied transformation-induced plasticity (TRIP) duplex steels (DP). TRIP DP are the first generations advanced high-strength (AHSS). AHSSs multiphase microstructures that ensure advantageous combination strength ductility. The Q&P process obtain a mixed microstructure with martensite ...
