Advanced Functional Materials for Marine Energy Utilization

open access: yesInterdisciplinary Materials, EarlyView.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

Interface Microstructures and Bond Formation in Ultrasonic Consolidation [PDF]

open access: yes, 2007
The quality of ultrasonically consolidated parts critically depends on the bond quality between individual metal foils. This necessitates a detailed understanding of interface microstructures and ultrasonic bonding mechanism.

A Comparison of Classical Constitutive Models for High‐Entropy Alloy Behavior: Effects of Medium Strain Rates and Temperature on Plastic Flow

open access: yesMaterials Genome Engineering Advances, EarlyView.
Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...

Tool For Friction Stir Tack Welding of Aluminum Alloys [PDF]

open access: yes
A small friction-stir-welding tool has been developed for use in tack welding of aluminum-alloy workpieces. It is necessary to tack-weld the workpieces in order to hold them together during friction stir welding because (1) in operation, a full-size ...

Comparing the In‐Plane Shear Behavior of Glass Fiber‐Reinforced and Carbon Fiber‐Reinforced Polymer Laminates With the Same Epoxy Matrix System in ±45° Tensile Tests

open access: yesPolymer Composites, EarlyView.
Schematic illustration of ±45° tensile testing, including detection of first‐ply failure (FPF) by optical crack detection and acoustic emission monitoring, comparison of FPF values with ASTM D3518 and D3039 criteria, and resulting ply level stress states at FPF for GF‐ and CF‐epoxy laminates.

Effect of welding parameters on microstructure and high temperature tensile properties of FGH96 superalloy inertial friction welded joints

open access: yesJournal of Aeronautical Materials, 2019
This study aims to evaluate the FGH96 superalloy joints fabricated by inertia friction welding (IFW) in different welding parameters, such as initial rotational speed and axial friction pressure, where the moment of inertia remained constant.
