Effect of tensile stress on corrosion behavior of 13Cr martensitic stainless steel

open access: yes工程科学学报, 2019
Tubes in deep wells are subjected to the mixed effects of the environment and stress and thus suffer many failures. Therefore, studying the corrosion of materials under stress deformation is necessary. This paper aims to investigate the effect of applied

LATH MARTENSITES IN LOW CARBON STEELS

open access: yesLe Journal de Physique Colloques, 1982
The morphology and crystallography of lath martensite in low and medium carbon steels have been studied by transmission electron microscopy and diffraction. The steels have microduplex structures of dislocated lath martensite (a < b ≪ c) with fairly straight boundaries and continuous interlath thin films of retained austenite.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Martensitic Transformations in Stainless Steels

open access: yesProgress in Physics of Metals, 2022
Currently, the direction of materials’ research, in which the martensitic transformations are observed, is intensively developed. This is due to the fact that, in the martensitic-transformation process, various defects of crystal structure (twins, dislocations, packaging defects, etc.) are formed in many materials, which together with grain ...

Defect Evolution and Mechanical Performance of Fused Filament Fabrication‐Manufactured 17‐4PH Stainless Steel Revealed by X‐Ray Computed Tomography

open access: yesAdvanced Engineering Materials, EarlyView.
X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...

An Integrated NLP‐ML Framework for Property Prediction and Design of Steels

open access: yesAdvanced Science, EarlyView.
This study presents a data‐driven framework that uses language‐processing techniques to interpret steel processing descriptions and machine‐learning models to predict mechanical properties. By organising complex process histories into meaningful groups and enabling rapid property forecasts, the work supports faster, more informed steel design through ...
