Quick Overview
A high level of interest in new, environmentally friendly propulsion technologies inevitably leads to a significant demand for H2 supply systems. By developing new titanium alloys that are better suited for use in hydrogen-containing environments, the Ti-Star research project supports the introduction of all kinds of innovative propulsion systems.
Given the excellent specific properties of titanium materials, it is desirable to use them in hydrogen-containing environments in the mobility sector. However, contact with hydrogen can lead to the formation of a brittle hydride phase, which causes premature failure and is generally known as hydrogen embrittlement of titanium materials. As a result, the use of currently known titanium alloys such as Ti-6Al-4V has been severely limited.
This is where the project comes in, investigating the influence of specifically selected alloying elements on the behavior of titanium materials under hydrogen conditions, with the goal of developing a novel alloy for the applications described, which will enable the Hanseatische Warenhandelsgesellschaft to expand its product portfolio and tap into new markets. A promising approach to reducing the material’s susceptibility to hydrogen embrittlement is the incorporation of other hydride compounds that have a less embrittling effect and, due to their higher affinity, prevent the formation of titanium hydrides.
