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...

In terms of the current trend research and development new materials optimization in automotive industry, greatest attention is paid to progressive high-strength dual-phase (DP) steels with increased stampability, which are designed for cold stamping specific internal car body components market. New grades DP provide a combination high strength good formability contribute weight savings vehicle...

In this study, a multi-element microalloyed GCr15Si1MoNbV bainitic bearing steel was designed by adding trace amounts of Nb and V. The bainite/martensite/retained austenite/undissolved carbide multiphase with short heat-treated cycle remarkable comprehensive mechanical properties prepared via low-temperature austempering, which compared traditional quenched tempered martensitic microstructure. ...

The determination of orientation relationships in dual or multi-phase materials is very important the field interface engineering for design with tailored properties. In this work, a code developed automated and statistical analysis relationship electron backscatter diffraction data. applied to example Fe-Ni-(Si)-C alloys containing lenticular martensite retained austenite, it shown that (OR) c...
