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

Effect of Q&P Process on 0.15C-MnSi Steels [PDF]
The present study is focused on analyzing the effect of Mn amount on two experimental steel compositions, specially designed for Q&P (Quenching and Partitioning), 0.15C-2.5Mn-1.5Si and 0.15C-3Mn-1.5Si without significant contribution of Al.

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
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 ...

Effect of ferrite phase fraction on bainite transformation plasticity in double transformation
Transformation plasticity significantly affects the stress distribution of a forging after heat-treatment. In this study, the transformation plasticity in a multi-phase transformation was measured experimentally.

A new austempering approach following intercritical austenitizing is explored to improve the mechanical behavior of API 5CT steel. By tailoring ferrite–bainite microstructures, the process achieves a balance of strength and ductility without the need for post‐quench tempering. The results highlight a cost‐effective alternative to conventional quenching

Acoustic emission is used here to study melting and solidification of embedded indium particles in the size range of 0.2 to 3 um in diameter and to show that dislocation generation occurs in the aluminum matrix to accommodate a 2.5% volume change.

Thermomechanical Processing, Microstructure, and Mechanical Properties of Medium‐Mn Steel
The microstructure evolution and mechanical properties of a medium‐Mn steel are investigated after thermomechanical processing and isothermal holding at various temperatures. A fine multiphase structure of bainite, fresh or tempered martensite, and retained austenite are obtained.
