Hydrogen Embrittlement of Ultrafine-Grained Austenitic Stainless Steels

open access: yesReviews on Advanced Materials Science, 2018
The effect of electrochemical hydrogen-charging on tensile properties, mechanisms of plastic deformation and fracture micromechanisms was studied using two ultrafine-grained (UFG) Cr-Ni austenitic stainless steels.

Laser heat treatment of martensitic steel and dual-phase steel with high martensite content

open access: yesMaterials Science and Engineering: A, 2019
Laser heat treatment of galvanised steels with a martensite content superior to 80% were performed on a 1 cm wide area over an extensive temperature range [620 K - 1350 K]. The material softening induced is studied through uniaxial tensile testing and SEM microstructural observation. A treatment temperature close to Ac3 yields a massive increase in the

Work hardening behavior in a steel with multiple TRIP mechanisms

open access: yes, 2012
Transformation induced plasticity (TRIP) behavior was studied in steel with composition Fe-0.07C-2.85Si-15.3Mn-2.4Al-0.017N that exhibited two TRIP mechanisms.

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

open access: yessteel 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 ...

Unprecedented strength in pure iron via high-pressure induced nanotwinned martensite

open access: yesMaterials Research Letters, 2019
Martensitic transformation can easily induce a maximum hardness value of 800–900 HV (Vickers hardness) for steels with carbon contents of 0.6 wt.% and above.

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

open access: yessteel 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 ...

Effect of applied magnetic field on wear behaviour of martensitic steel

open access: yesJournal of Materials Research and Technology, 2019
The effect of applied magnetic field on wear resistance of martensitic steel with different dislocation densities has been investigated. The wear resistance of martensitic steels improved under the applied magnetic field, while the improvement reduced as

Continuous Cooling Transformations in Martensitic Stainless Steels.

open access: yesISIJ International, 1994
To gain further insight into the nonequilibrium transformations produced by non-isothermal cycles in martensitic stainless steels, the study experimentally determined the CCT diagrams of four Cr13 and CrMoV14 type steels, which were cooled from two different austenizing temperatures.

Fatigue Strength in Additive Toolmaking: A Study of Metal Binder Jetting and Electron Beam Melting for Processing Carbide‐Rich Cold‐Work Tool Steels

open access: yessteel research international, EarlyView.
Focusing on the critical tap hole region of the blast furnace, this work examines binder characteristics, prepares tap hole clay with different formulations, and evaluates their physical properties. The findings confirm the advantages of composite binders and offer a new binder option for tap hole clay.
