In-situ diffraction Mo(Si,Al)2 for sustainable heating applications
Research Project, 2021 – 2023

Purpose and goal
The purpose of the project is to investigate the possibilities offered by neutron and synchrotron diffraction for innovation and development of tailor-made materials for electrification of industrial heating processes. Specifically, we want to investigate whether it is possible to measure crystal direction-dependent thermal expansion of the different phases in ceramic heating elements based on Mo (Si,Al)2 at temperatures up to 1500 ° C. The aim is to verify the methods for use in industrial alloy development projects.

Expected results and effects
Verification of the methods creates opportunities for Kanthal to integrate advanced characterization techniques in their portfolio. As these methods provide access to information that is not accessible in other ways, it provides increased opportunities for knowledge-driven development and innovation, and thus a direct competitive advantage.

Planned approach and implementation
The properties of interest (anisotropic phase-specific thermal expansion and internal strains up to 1500 °C) will be measure using both in-situ diffraction with synchrotron radiations and neutrons. The two methods have complementary benefits and drawbacks, and a direct comparison will allow Kanthal to make informed decisions for future use of large scale facilities and integration of the techniques into the R&D process. The experiments will be jointly performed by Kanthal and Chalmers, which gives the company direct experience of both execution and analysis.
