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.

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 ...

Localized Laser Heat Treatment on AISI 1045 Steel Using a LPBF Laser
Engineering Reports, Volume 7, Issue 1, January 2025.A LPBF laser was used to locally heat‐treat the surface of normalized AISI 1045 steel bars. While sections of overheating were seen, adaptations of previously published energy density models were able to determine valid parameters to create a hardened martensitic surface.

Improving lightweight materials processing for automotive by using intercritical annealing [PDF]
MATEC Web of Conferences, 2018 “Fat men cannot run as fast as thin men, but we build most of our vehicles as though deadweight fat increased speed…. I cannot imagine where the delusion that weight means strength came from….” - Henry Ford. Fuel efficiency and safety innovations are the most important consumer consideration purchasing a car.

Materials Characterization, 2019 Abstract The quenching and partitioning response of intercritically annealed steel with aluminum contents in the 2–3 wt.% range and a carbon content of 0.2 wt.% was studied. Two types of morphologies for retained austenite were observed in electron backscatter diffraction studies: blocky, untransformed austenite grains and partially transformed ...
