Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

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.

Practical Wave Power Generation System.

Journal of the Magnetics Society of Japan, 2002
We developed a new type of wave power generation system. In this system, water valves without mechanical operation are combined with air chambers. A test plant was installed on the south breakwater at Haramachi thermal power station, and testing for practical use was carried out at the Haramachi site from 1996 until 2000.

Power Generation from Tides and Waves

, 2022
AbstractMarine renewable energy generated from ocean tides and waves has not yet reached wide spread deployment or full commercial availability on par with comparable sources. This handbook chapter describes the global development of marine renewable energy technology and the most promising commercialization pathways, including “blue economy” marine ...
