 This study demonstrates how the addition of a specific type of atom can be used to simultaneously increase the strength and toughness of a material. The researchers found that when a certain type of atom with a lower electronegativity was added to a transition metal boride, it caused the material to become harder while also increasing its ability to absorb energy without breaking apart. This discovery could lead to new materials with improved mechanical properties, such as nitrides and carbides. This article was authored by Sheen Legu, Chang Liu, Xingxing Gao, and others.
