High‐throughput investigation of processing–microstructure relation in quenching and partitioning steels via gradient heat treatment and rapid characterization

Materials Genome Engineering Advances, Volume 3, Issue 3, September 2025.
This study proposes a novel high‐throughput experimental method integrating gradient heat treatment and advanced characterization techniques. This method can efficiently establish the processing–microstructure relation in quenching and partitioning steels. As quenching temperature decreases, the fraction of retained austenite initially increases due to

Status and Progress of Super-Bainitic Steels

Teshugang, 2012
The basic alloying elements in super-bainitic steels are C-Mn-Si and the structure of ultra-fine bainite, martensite and residual austenite is obtained by low temperature phase transformation at 300 〜500 ℃. In order to decrease critical cooling velocity,

Influence of Aluminum on Microstructure and Mechanical Properties of Air‐Hardened Medium Manganese Steel

steel research international, Volume 96, Issue 7, July 2025.
This article investigates the influence of aluminum concentrations on the microstructure and mechanical properties of air‐hardening ductile steels. The reduction of the aluminum contents below 0.5 wt% is unfavorable as it does not ensure sufficient toughness.

Impact of Partitioning Temperature Parameters during the Quenching and Partitioning Process on Medium Carbon Steels with Two Different Alloying Strategies

steel research international, Volume 96, Issue 6, June 2025.
The study investigates microstructural evolution during high‐temperature partitioning in medium‐carbon, high‐silicon aluminum‐aided steels, exploring phase transformations affecting the final microstructure. Quenching and partitioning processes, with varying primary martensite fractions, reveal significant austenite stabilization at 350 °C, but ...
