Advanced high strength steel (AHSS) TWIP: A door to the future in metal forming [PDF]

AIP Conference Proceedings, 2012
The last decades have been characterized by a fast evolution of cars. This work shows the evolution of vehicle weight. It shows the response of car manufacturers using new materials and production methods that allow lighter vehicles with lower consumption, cheaper and with lower influence on the greenhouse effect.

Microstructural Evolution and Mechanical Properties of a Medium‐Manganese Steel Manufactured by Laser‐Based Powder Bed Fusion of Metals

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.
Fe–12Mn–0.2C medium‐manganese steel is processed by laser‐based powder bed fusion of metals using blended as well as pre‐alloyed powder. Various scanning speeds are used to determine the influence of energy deposition rate on microstructure and mechanical properties.

The Influence of Subcritical Annealing and Cold Working on the Hydrogen Embrittlement Susceptibility of X65 D Pipeline Steel

Materials and Corrosion, Volume 76, Issue 10, Page 1478-1496, October 2025.
This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.

Investigation on Crystallization of CaO‐Al2O3‐B2O3‐BaO Slag Using Differential Scanning Calorimeter and In Situ High‐Temperature Raman Spectroscopy

steel research international, Volume 96, Issue 8, August 2025.
The crystallization of CaO‐Al2O3‐B2O3‐BaO glassy slags was investigated by multiple research techniques. The partial replacement of calcium oxide by barium oxide inhibits the crystallization ability of slag, which contributes to the development of “nonreactive” mold fluxes for high‐aluminum advanced steel continuous casting.

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 ...

The Effect of Bake Hardening on Quenched and Partitioned AISI 420 Stainless Steel

steel research international, Volume 96, Issue 5, May 2025.
The effect of bake hardening (BH) on the mechanical properties of quenched and partitioned stainless steel is studied. Suitable Q&P parameters are first determined, and subsequent BH with and without prior deformation is investigated. The results indicate that standard BH2 treatment can significantly alter the mechanical properties, suggesting that BH ...

Effect of Austenite Reversion Treatment and Partitioning on the Phase Transformation Behavior and Mechanical Properties of Martensitic–Austenitic CrMnNi‐Cast Steel

steel research international, Volume 96, Issue 5, May 2025.
The effect of austenite reversion treatment (ART) on the phase transformation behavior and the mechanical properties of the martensitic–austenitic stainless X16CrNiMnN15‐3‐1‐transformation‐induced‐plasticity‐cast steel is investigated. It is further shown that an ultrahigh‐strength steel with good ductility can be achieved by subsequent partitioning at

Edge crack sensitivity versus tensile local ductility of AHSS sheet steels

IOP Conference Series: Materials Science and Engineering, 2020
Abstract There is a growing interest in correlating usual tensile testing results with edge crack sensitivity testing from punched ISO16630 hole expansion ratio HER (10mm shear cut hole, 12% clearance, conical expansion tool). A new kind of tensile local ductility parameter has been developed lately based on broken sample surface of ...

Local shear fracture properties in heat-affected zone of resistance spot-welded advanced high-strength steel

Journal of Materials Research and Technology
In the process of resistance spot welding of advanced high-strength steel (AHSS), the development of heat-affected zones (HAZs) considerably modifies the mechanical properties of the weld region.
