The properties of flash- evaporated films of GaAs
and GaP were studied in this investigation. Films were
grown at various substrate temperatures, source temperatures,
source-to-substrate distances and rates of deposition
and were evaluated as to their structural,
optical and electric properties.
It was found that substrate temperature was the
major...
The zirconium-chromium phase diagram was investigated in the
region between 40% and 85% chromium. The ZrCr₂ intermetallic
compound which has been the source of some controversy was especially
considered. It was found that ZrCr₂ transforms from the low
temperature C-15 (MgCu₂, FCC) structure to the high temperature
C-14 (MgZn₂, HCP)...
Solid solution alloying was employed in an attempt to produce some
relatively ductile form of beryllium. If the c/a ratio could be significantly
altered, it was felt new or different slip systems could be activated. The
following elements were selected on the basis of atomic size, melting point,
crystal structure...
