Numerical simulation of local cooling on residual stress and deformation of welded joints of unequal thickness plates

open access: yesJournal of Materials Research and Technology
To address the significant variations in stress distribution and welding deformation of unequal thickness plate welded joints, this study investigates the effect of local cooling on residual stress and welding deformation through experiments and ...

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Mechanical and molecular structure essence of deformation differences in organic macerals of tectonically deformed coal

open access: yesMeitan xuebao
The heterogeneity of coal microdeformation has a significant impact on the occurrence and migration of coalbed methane, and the difference in organic maceral deformation is the key to analyzing coal microdeformation. To date, there are few studies on the

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

open access: yesAdvanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Isolating the influence of residual stress on tensile behaviour of laser-based powder bed fusion Ti alloys via mechanical stress relief

open access: yesAdditive Manufacturing Letters
This study proposes a mechanical stress relief (MSR) process to reduce the residual stress in PBF-LB materials. It involves progressive, slow cyclic loading in the material’s elastic region.
