In this paper we analyze mesodefects accumulating during plastic deformation on the faceted high angle grain boundaries. It is shown that the system of mesodefects can be represented as a set of linear mesodefects of the rotational type (junction disclinations), and planar mesodefects of the shear type (uniformly distributed dislocations with Burgers vector lying in the plane of the facet). The process of formation of broken dislocation boundaries in the elastic fields of various configurations of the abovementioned mesodefect

Typical configurations of broken dislocation boundaries formed during plastic deformation at faceted grain boundaries have been analyzed. The reasons for their formation have been determined. It has been shown that the shape and sizes of strain-induced broken dislocation boundaries can be determined by the geometry of a faceted boundary and the relevant slip systems of ...

Superplastic deformation behaviour of conventional sheets of a near-α titanium alloy (Ti-2.5Al-1.8Mn) was studied by a step-by-step decrease of the strain rate and constant strain rate tests in a temperature range of 790–915 °C. The research found that superplastic deformation is possible in a temperature range of 815–890 °С and a constant strain rate range ...

Organometal triiodide perovskites are promising, high-performance absorbers in solar cells. Considering the perovskite as a thin film absorber, we solve transport equations and analyse the efficiency of a simple heterojunction configuration as a function of electron–hole diffusion lengths. We found that for a thin film thickness of ~1 micron the maximum efficiency of ~31% could ...
