Static recrystallization characteristics and kinetics of high-silicon steels for direct quenching and partitioning [PDF]

, 2019
In the direct quenching and partitioning (DQ&P) process,tough ultra-high-strength steel is made by combining thermomechanical processing with quenching and partitioning to obtain martensite toughened by thin films of retained austenite.

Microstructure and mechanical property relationship in a high strength high-Al low-Si hot-dip galvanized steel under quenching and partitioning process

Journal of Materials Research and Technology, 2020
We elucidate here profound effects of quenching and partitioning process on the microstructure and mechanical properties of high strength hot-dip galvanized steel with high Al and low Si content. The results indicated that partitioning time significantly

Critical Assessment 7: Quenching and partitioning [PDF]

Materials Science and Technology, 2015
Quenching and partitioning is a relatively new heat treatment concept to generate microstructures containing retained austenite stabilised by carbon partitioning from martensite. Research on quench and partitioning has been conducted by numerous groups, and this critical assessment provides some of the authors’ perspectives on progress and ...

Development of a new generation of quench and partitioning steels: Influence of processing parameters on texture, nanoindentation, and mechanical properties

Materials & Design, 2020
A novel quenching and partitioning process (Q&P) including the hot stamping (HS) process was studied, using two stamping temperatures (750 °C and 800 °C) and two quenching temperatures (318 °C and 328 °C). This combination is here called Hot Stamping and
