Abstract: Strain glass is a glassy state with frozen ferroelastic/martensitic nanodomains in shape memory alloys, yet its nature remains unclear. Here, we report a glassy feature in strain glass that was thought to be only present… read more here.

DOI: 10.1088/1361-6463/abe3b0
Abstract: Fe doping in Ni2Mn1.5In0.5 results in suppression of the martensitic phase via two contrasting routes. In Ni2Mn1.5 − x Fe x In0.5, the martensitic phase is converted to a strain glassy phase, while in Ni2 − y Fe y… read more here.

DOI: 10.1103/physrevlett.130.116102
Abstract: Ceramics, often exhibiting important functional properties like piezoelectricity, superconductivity, and magnetism, are usually mechanically brittle at room temperature and even more brittle at low temperature due to their ionic or covalent bonding nature. The brittleness… read more here.
