Venue: Conference hall, bld. 42а, Frank Laboratory of Neutron Physics

Seminar topic: “Development of crystallographic textures at high pressures”

Speaker: Roman Vasin

Abstract:

The investigations of crystallographic textures – the preferential orientations of grains composing a polycrystal at high pressures using the synchrotron radiation diffraction with the use of a diamond anvil cell in radial geometry (rDAC) are presented in the report. The peculiarities of development of the texture during plastic strain deformations, structural phase transitions with a choice of options, as well as the resulting limitations on the yield strength of materials are considered using the example of some alloys (Fe-Si, Ni₃Al), cement components and others.
