Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

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

Thermodynamic Modeling of Sn–C and Fe–Sn–C Systems for the Tramp Elements Control in Steel Production

steel research international, EarlyView.
A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

steel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
