Martensitic phase-transforming ceramics can undergo reversible phase transformations under thermo-mechanical stimuli, yet brittle in their monolithic, polycrystalline form. Incorporating these ceramics into matrices thereby metastabilizing austenite gives rise to a significant toughening effect by t...
