Microstructural Refinement in a Low Alloy High Strength Martensitic Steel [PDF]

Metallography, Microstructure, and Analysis
Abstract The prior austenite grain (PAG) size of a low alloy high strength martensitic steel, AF9628, was refined by rapid austenitizing heat treatments at 825 and 850 °C. The reduction in PAG size of as high as 97% was obtained. After one rapid austenitizing cycle, the newly nucleated (small) PAGs were observed to be preferentially located ...

The Mechanism of High-Strength Quenching-Partitioning-Tempering Martensitic Steel at Elevated Temperatures

Crystals, 2019
High-strength medium-carbon martensitic steel was heat treated through a quenching-partitioning-tempering (Q-P-T) treatment. Both the mechanism for improved ductility and the high temperature stability of austenite were investigated.
