Dispersion hardened alloys of Pt and Au containing ThO2 and Al2O2 were made and tested. These alloys were made by precipitating the elements from a solution containing a suspension of the oxide phase. The precipitate deposited on the oxide particles,

Simple (100) tilt, twist, and double-tilt bicrystals of NaCl, grown by the Kyropoulos technique from melts of high-purity NaCl, alone and with controlled impurity additions, were examined for mechanical strength and structure of the grain boundaries.

Techniques are described for the growth of large (6.3 cm2 by 15 cm) single crystals and bicrystals of NaCl. Grain boundaries from 2 to 45° mismatch across the interface were grown for pure tilt and pure twist misorientation in NaCl by the Czochralsk

Dispersion‐strengthened alloys of copper containing 2.2 and 5.0 vol% ThO2 were made by precipitating copper from a stirred solution of copper acetate containing a suspension of submicron‐sized ThO2 particles. This procedure produced alloys of goo

Thin films of carbon or of silicon monoxide were observed while heated to 1000°C inside the electron microscope. Spherical graphite nuclei, approximately 200 A in diameter, appear at 200°C in the carbon films. These nuclei maintain their spherical

Thin films of vapor‐deposited nickel and gold, supported only by copper grids, were annealed inside the electron microscope. The microstructures were recorded as a function of temperature. The originally continuous thin films of nickel (150 A thick
