Universal symmetry property of point defects in crystals
Xiaobing Ren,Kazuhiro Otsuka +1 more
TL;DR: In situ transmission electron microscopy finds clear evidence for the existence of a universal symmetry property of point defects; this symmetry-conforming property can lead to various interesting effects including "aging-induced microstructure memory" and the associated "time-dependent two-way shape memory".

Analysis of nonisothermal transformation kinetics; tempering of iron-carbon and iron-nitrogen martensites
TL;DR: In this paper, a non-isothermal analysis of the temperature corresponding to a fixed stage of transformation is measured as a function of heating rate, which removes constraints imposed unnecessarily on so-called Kissinger-like procedures.

Pressure‐enhanced crystallization kinetics of amorphous Si and Ge: Implications for point‐defect mechanisms
TL;DR: In this paper, a kinetic analysis of the Spaepen-Turnbull interfacial dangling bond mechanism is presented, assuming thermal generation of dangling bonds at ledges along the interface, independent migration of the dangling bonds along the ledges to reconstruct the network from the amorphous to the crystalline structure, and unimolecular annihilation kinetics at dangling bond "traps".
