Thermal evolution of yttrium tetraboride thin films – A candidate for high temperature applications

The common drawback of ceramic transition-metal boride films, the inherent brittleness, limits their practical applications under thermal load. Yttrium tetraboride (YB4), having a high melting temperature, chemical inertness, high hardness, and low Young's modulus of elasticity in the bulk form...
