Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Density Measurement of Irradiated and Nonirradiated Zirconium Oxide by Ptychographic X‐Ray Computed Tomography (PXCT)

Advanced Engineering Materials, EarlyView.
Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

Study on the Corrosion Behaviours of X80 Pipeline Steel Joints Fabricated via Hot-Wire Tungsten Inert Gas Welding

International Journal of Electrochemical Science, 2019
X80 pipeline steel joints were fabricated via hot-wire tungsten inert gas welding by using ER70S-G wire with a diameter of 1.2 mm. The microstructures of the welded joints were analysed by using metallographic microscopy.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Calculation Method for the Heat Affected Zone of Coiled Tubing Circumferential Welding

Shiyou jixie, 2019
Coiled tubing circumferential welding is indispensable in the manufacturing and on-site repair process. The heat-affected zone caused by welding not only directly reduces the overall strength of the coiled tubing, but also makes the coiled tubing more ...

Study on ductile fracture of electroslag welding and its heat affected zones

Hanjie xuebao
Electroslag welding involves high heat input, which may cause material hardening in the weld and heat-affected zone. At the same time, the electroslag weld is in an inaccessible state, making the welding quality difficult to control.
