Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

steel research international, EarlyView.
Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

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

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 ...
