No Alpha-Case Layer to Fear Anymore with Titanium

The properties of the components further underscore the technological leap forward. A fracture elongation of over ten percent was achieved without additional heat treatment following the deep-drawing process. Additionally, the results suggest that multi-stage forming processes could be performed in the future without intermediate heat treatment—initial two-stage trials have already been successful, according to Ranshofen. Another advantage is that no brittle Alpha Case layer forms on the component surface, which is explained by the comparatively short high-temperature exposure. An Austrian patent has already been granted for the process, and an international patent application is currently underway. This strategic protection provides a foundation for further establishing titanium forming at moderate temperatures as a resource-efficient solution in industrial applications.
