Fundamentals of grain and interphase boundary diffusion

TL;DR: In this article, the distribution of internal residual stresses of the first kind during the repeated hot deformation was studied using X-ray dosimetry with Xray spectral analysis, and it was shown that after repeated thermal deformation, the sample under study transforms from a viscoelastic Maxwell material into a Kelvin-Voigt material, which facilitates structural stabilization.

TL;DR: In this article, conductivity relaxation experiments have been performed on n-type barium titanate ceramics, co-doped with Y (donor) and Mn (acceptor), as a function of temperature (700 −900 °C) and oxygen partial pressure (0001 −10 bar) by employing the van der Pauw technique.

TL;DR: Interfaces between the tiny crystal grains that make up solid copper have been shown to change from one ordered phase to another, independently of the phase adopted by the crystals, opening up prospects for materials development.

TL;DR: Grain boundary diffusion in a Ni–Cr–Mo alloy is influenced by the interplay of segregation, precipitation and interface structures. The microstructure evolution and diffusion rates are controlled by the specific states of segregation-precipitation-structure achieved through annealing treatments.
