[en] The effects of temperature and strain rate on faulting mode for potassium hydrophthalate (KNC8H4O4) single crystals under compression in two different directions are investigated. These organic crystals are widely used as dispersing elements in X-ray spectral devices to study long-wave X radiation. It is shown that the mechanism of crack formation in faulting dependents on crystal orientation. The faulting is considered to be one of the types of rotational deformation

Исследуется влияние температуры и скорости деформирования на характер сбросообразования в монокристаллах гидрофталата калия (KNC8H4O4) при их сжатии в двух разных ориентациях. Эти кристаллы применяются в качестве диспергирующего элемента в рентгеноспектральных приборах для исследования длинноволнового рентгеновского излучения. Показано, что механизм образования трещин при сборосообразовании зависит от ориентации образца. Отмечается, что сбросообразование можно считать одной из мод ротационной деформацииJournal
[en] Large-diameter single crystals of TeO2 are grown by the Czochralski method in specially designed setups with automatic monitoring of the crystal growth. The degree of perfection of the grown crystals is examined using selective etching and X-ray topography (the Shultz method). The temperature dependence of the microhardness of TeO2 single crystals is investigated for different crystallographic planes, namely, (001), (100), and (110)

[en] It has been carried out the investigation of the mosaic structure of ZnO crystals by two methods providing the information on mosaic structure and inner stresses (γ-ray diffraction and conoscopic method). It has been observed a certain correlation between the results obtained by the two methods. (author)
