Abstract: We propose and analyze a simple variational model for dislocations at semi-coherent interfaces. The energy functional describes the competition between two terms: a surface energy induced by dislocations and a bulk elastic energy, spent to… read more here.

Abstract: Abstract The β1′and β2′ are important precipitates in Mg-Zn alloys. Two types of precipitates both are composed of MgZn2, but the orientation relationships of MgZn2 with the α-Mg matrix in two precipitates are different. To… read more here.

DOI: 10.1126/science.abq7490
Abstract: Covalently bonded ceramics exhibit preeminent properties—including hardness, strength, chemical inertness, and resistance against heat and corrosion—yet their wider application is challenging because of their room-temperature brittleness. In contrast to the atoms in metals that can… read more here.
