Phase stability of tungsten boride for fusion reactor shielding

Tungsten boride is an attractive material for shielding high-energy neutrons in a fusion reactor because the boron absorbs the neutrons, and the tungsten stops the gamma rays. This project has researched the crystal structure, the exact composition and the phase stability of the epsilon phase in the tungsten boron system so that fusion reactor developers and cutting-edge fusion startup companies can properly include this material in their design calculations.
