Stress Corrosion Behavior of X65 Steel Welded Joint in Marine Environment

International Journal of Electrochemical Science, 2015
The short-term stress corrosion cracking (SCC) behavior of X65 pipeline steel welded joints in simulated deep (1000 m) and shallow sea was studied by the immersion of U-shaped bend samples, electrochemistry, and scanning electron microscope observation ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Enhanced high-temperature oxidation resistance of Mg-Gd-Zn-Zr alloy by YSZ TBC with PEO bond layer

npj Materials Degradation
Magnesium alloys suffer from significant limitations in high-temperature applications due to poor oxidation resistance, primarily attributed to the non-protective nature of their native MgO scale (Pilling–Bedworth ratio, PBR = 0.81).

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Multifunctional water-based surface tolerant coating and its protective performance

工程科学学报, 2015
Based on carbon steel surface corrosion,a study was conducted on multifunction acid water-based surface tolerant coatings. The focus was placed on the effect of antirust components and preparation processes on the coating properties. The barrier property

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.

Inhibition Film Formed by 2-mercaptobenzothiazole on Copper Surface and Its Degradation Mechanism in Sodium Chloride Solution

International Journal of Electrochemical Science, 2016
Copper surface was modified by 2-mercaptobenzothiazole (MBT) dissolved in isopropanol for the first time. The interaction between MBT and copper, the corrosion inhibition effect of film formed by MBT on copper surface together with its dynamic evolution ...

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

Advanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...
