"Grids of Dislocations Formed During Growth and Annealing in Base Plane of
Zinc Single Crystals"
Moscow, Kristallografiya, Vol 18., No 2, Mar-Apr 73, pp 418-420.
Abstract: P-rimary attention in this work is given to,the study of the n-qtLll*C
of the dislocations and determination both of Burgerls,vectors and direc-
tion vectors dl of segments of dislocation grids. Studies were performed
using a GEM-100V electron microscope at 100 kv accelerator voltago. Analysis
of the pictures produced showed that the dislocation gfrid,; consist mainly of
mixed dislocations.. Over 20 grids~%qere studicd and in all cases it was found
that the orientation of segnwits of dislocations was near edge orientation.
This fact might be related to the process~.of preparation of specimens, since
dislocation structures of helical segments might easily breakdown in the thin
foil due to transverse slipping, while noncon-servative motion i!; required for
projection of edge segnents Afrom the., plane, of, tho gri.d.

Translation; Slanting shells 0~

right angles are considered. Ifne longitudinal edge elements of the shell were
supported during the experiment. The experimental inyeztigations were conducted
on a series of models OPO%60cm) of a reinforced cemxntu solution 1:25, Stress-
