DOI: 10.1016/j.actamat.2019.07.028
Abstract: Abstract Cracking is generally regarded as an unavoidable consequence of martensitic transformation in polycrystalline ZrO2-based ceramics. This shortcoming has limited ZrO2-based shape-memory ceramics (SMCs) to micron-sized single- or oligo-crystals to reduce bulk transformation stresses. In… read more here.
