TL;DR: In this article, a detailed characterization of the microstructural development of a new quenching and partitioning (Q&P) steel was presented, which showed that stabilization of austenite can be achieved at significantly shorter time scales via the Q&P route than is possible via a bainitic isothermal holding.

TL;DR: In this paper, an improved X-ray diffraction line profile analysis method is developed to determine dislocation density of lath martensitic steels, which combines the modified Warren-Averbach (MWA) and the modified Williamson-Hall (MWH) methods.

TL;DR: In this article, the quenching and partitioning of a low-carbon steel containing 1.1-wt pct aluminum by heat treatments consisting of partial austenitization at 900 −°C and subsequent rapid cooling to a quench temperature in the range between 125 −C and 175 −C, followed by an isothermal treatment (partitioning step) at 250 −C for different times.

TL;DR: In this paper, the application of the Quenching and Partitioning (Q&P) process to two low-carbon steels has led to the development of a new kind of steel microstructure formed by laths of martensite separated by films of intercritical ferrite and retained austenite.

TL;DR: In this article, a theoretical design procedure based on phase transformation theory alone has been successfully applied to design steels with a microstructure consisting of a mixture of bainitic ferrite and retained austenite.
