steel research international, EarlyView.On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Metals, 2019 Hot-stamped ultra-high strength steels have been widely used in automobile structural parts. Considering the high splash tendency in resistance spot welding due to their extremely high hardness, in this work, microstructural characteristics and ...

steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Interior Nucleation of Martensite in a Cubic-to-Tetragonal Phase Transformation
, 2015 Using a variational model based on non-linear elasticity we investigate whether in a cubic-to-tetragonal phase transformation it is energetically preferable to nucleate martensite within austenite.

steel research international, EarlyView.Here, the microstructure evolution of a new generation ultrahigh‐strength S1300‐type structural steel has been investigated for direct‐quench and tempering route. Various stages of tempering are elucidated by thorough characterization, and a new strain‐size parameter of martensite is proposed to have a correlation with hardness, which will be useful in

Droplet Fluctuations in the Morphology and Kinetics of Martensites
, 1996 We derive a coarse grained, free-energy functional which describes droplet configurations arising on nucleation of a product crystal within a parent. This involves a new `slow' vacancy mode that lives at the parent-product interface.

Anisotropic Microstructure Evolution in Laser Powder Bed Fusion of 316L Stainless Steel Alloy
steel research international, EarlyView.This study investigates the anisotropic microstructure and mechanical properties of 316 L stainless steel processed via laser powder bed fusion. Differences in porosity, grain size, and dislocation density across three principal planes are examined. Findings reveal the impact of thermal gradients, lattice strain, and strengthening mechanisms on the ...

The role of phase interface energy in martensitic transformations: a lattice Monte-Carlo simulation
, 2014 To study martensitic phase transformation we use a micromechanical model based on statistical mechanics. Employing lattice Monte-Carlo simulations and realistic material properties for shape-memory alloys (SMA), we investigate the combined influence of ...

The onset of martensite and auto-tempering in low-alloy martensitic steels
, 2021 Abstract High-strength low-alloy martensitic steels provide low-cost environmentally efficient solutions for weight critical engineering. The wider use of such materials will provide energy savings and reduce the carbon footprint of many products. They offer a combination of both good weldability and high strength, which makes them attractive materials

Martensite crystallography and chemistry in dual phase and fully martensitic steels
Materials Characterization, 2018 Lath martensite is important in industry because it is the key strengthening component in many advanced high strength steels. The study of crystallography and chemistry of lath martensite is extensive in the literature, however, mostly based on fully martensitic steels.
