Formability of quenching-partitioning-tempering martensitic steel [PDF]

Heat Treatment and Surface Engineering, 2019
A Fe-0.20C-1.49Mn-1.52Si-0.58Cr-0.05Nb (wt%) steel was treated by a novel quenching-partitioning-tempering (Q-P-T) process and traditional quenching and tempering (Q&T) for comparison, respectively...

The Suitability of 42SiCr Steel for Quenching and Partitioning Process [PDF]

Manufacturing Technology, 2016
QP (quenching and partitioning) heat and thermo-mechanical treatment was applied to middle carbon, low alloyed CMnSiCr steel. Various numbers of deformation steps and different heating and cooling rates were tested for this steel. Two QP treatments were accompanied by subsequent annealing step at 250°C (QP-T processing).

The Effect of Quenching and Partitioning (Q&P) Processing on the Microstructure, Hardness, and Corrosion Resistance of SAE 9254 Spring Steel

Metals
In the present work, the effect of quenching and partitioning cycles on the microstructure, hardness, and corrosion behavior of SAE 9254 spring steel was investigated. Initially, the critical phase transformation temperatures were analyzed by dilatometry.
