Alloy development for Hydrogen-related applications; Part II (ALL4HYDRO II)

Important results from the project

The project investigated different alloy design strategies and their impact on the material performance in a hydrogen environment. The alloy design strategies were divided into two paths: (i) matrix or "bulk" with the aim of controlling hydrogen diffusion and effect in the bulk, and (ii) barrier oxide layers with the aim of reducing hydrogen uptake into the bulk. The project results provided a good basis for understanding the effect of different alloy design strategies on the hydrogen embrittlement behavior of metallic materials.

Expected long term effects

The project identified the most promising approach that can be further studied in future research projects. This will support future industrial implementation for relevant materials and cases.

Approach and implementation

Thanks to the smooth cooperation between all partners, the project was successful and followed the planned activities. One university staff member left the project halfway for personal reasons, resulting in a delay in progress. The project acted quickly and found a good postdoctoral replacement to continue the activities and get back on schedule.
