Advanced martensitic stainless steels for dental instruments

open access: yes, 2023
The developed microstructures and tensile strength of AISI 420-type martensitic stainless steels with different carbon content from 0.2 to 0.4% were studied after tempering at 450°C for 3 h and at 800°C for 16 h. The volume fraction of retained austenite

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

open access: yesMaterials and Corrosion, EarlyView.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

open access: yesMaterials and Corrosion, EarlyView.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Influence of Strain Rate on the Strain Hardening Behavior of a Lean Duplex Stainless Steel

open access: yesMetalMat, EarlyView.
The aim of this study was to examine how strain rate influences the compressive strain‐hardening behavior of a lean duplex stainless steel LDX 2101. Microstructural analysis using electron backscatter diffraction (EBSD) revealed a strain‐induced austenite‐to‐martensite transformation.

Application of Machine Learning in Heat Treatment Process Design of Carburized Steel

open access: yesMaterials Genome Engineering Advances, EarlyView.
To accelerate heat treatment design, we constructed a closed‐loop machine learning strategy involving multi‐source datasets and feature screening. The optimized model accurately predicts hardness and friction coefficients, successfully guiding the process optimization for two typical carburized steels with high experimental consistency.

Predicting the Ms temperature of lean alloyed ferritic–austenitic stainless steels

open access: yesJournal of Materials Research and Technology
A set of laboratory hot-rolled and thermally cycled 19–22 wt% Cr lean alloyed ferritic–austenitic stainless steels were studied with respect to calculated equilibrium austenite composition and experimental martensite start (Ms) temperature.
