Advanced Functional Materials for Marine Energy Utilization

Interdisciplinary 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 ...

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

Materials 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 ...

Residual Stress Analysis in Linear Friction Welded Ti17

Materials
Residual stresses with a complex distribution are generated after linear friction welding, which affects the service performance of the weldment. In this work, a numerical model for linear-friction-welded Ti17 (Ti-5Al-2Sn-2Zr-4Mo-4Cr) was developed to investigate the evolution of residual stresses and the effect of welding parameters on residual ...
