<p>Castable silicon-based compositions have enhanced toughness and related properties compared to silicon. The silicon-based compositions comprise silicon at a concentration greater than 50% by weight and one or more additional elements in structure comprising a cubic silicon phase and an additional phase which may impart toughness through mechanisms related to plastic flow or crack interaction with interfacial boundaries.</p>
