Time-dependent deformation behaviours of two stainless steels at elevated temperature: Correlation between slow strain rate and creep testing

European Journal of Materials
Austenitic stainless steels, such as Sanicro 25 and Sanicro 28, exhibit excellent mechanical properties at elevated temperatures. This study investigates their time-dependent deformation behaviours through two distinct testing methods: slow strain rate ...

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Numerical investigation on the stress corrosion cracking of FV520B based on the cohesive zone model

Results in Physics, 2019
Tensile failure process of plane specimens and unilateral V-notched specimens is simulated basing on cohesive zone model (CZM). The internal stress in corrosion scales and film-induced stress in matrix increases with the increase of corrosion scale ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation
