Influence of Higher Tramp Element Level on the Weldability of Automotive Steels
steel research international, EarlyView.The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

New Observations on Flash Bainite [PDF]
, 2016 Flash bainite is a new type of microstructure developed from new heat treatment process called “Flash Processing”. Using less treatment time, the result is the high performance steel with mixed microstructure of bainite and martensite.

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

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 ...

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 ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design
steel research international, EarlyView.Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...
