The tensile yield and fracture strengths of a structural steel have been measured before and after irradiation with neutrons. The fracture strength increases with irradiation at the same rate as the yield strength and the embrittlement cannot be ascribed to a loss of cohesive strength. Measurements have been made of t…

Measurements of elastic modulus and mechanical loss at audio-frequencies have been obtained on irradiated and nonirradiated specimens of polyhexamethylene adipamide over a broad temperature range extending from 80°K to 600°K. The irradiations were carried out at the Brookhaven and Penn State Reactors. The internal fri…
Spherulite growth rates have been measured in two polyamides, 66 and 6 nylon, at temperatures ranging from 38 to 141° below the melting points using a moving photomicrographic technique. At constant temperature, the spherulite radius increases at a constant rate. This isothermal growth rate constant is temperature dep…

The use of highly alloyed materials to combat corrosion is discussed and extensive data are given. The following molybdenum-bearing alloys are considered at length: nickel-molybdenum alloy, nickel-molybdenum-chromium alloy, and nickel-chromium-iron-molybdenum alloy. Attention is given also to cobalt-base alloys and si…

A liquid tin solution calorimeter has been constructed for determining the heats of formation of alloy phases from the heats of solution of the alloys and of the pure component metals in liquid tin. The design of the calorimeter is presented, and the experimental procedures and calculation methods are described and il…
The sulfide corrosion cracking behavior of Type 4140 bolts was studied in H2S-H2O systems at temperatures of 20 to 120 C and at pressures of 1 to 17 atmospheres. The susceptibility to cracking increased with increasing bolt hardness, increasing applied stress, increasing amounts of plastic deformation, and decreasing…

A study of the Zeeman effect of absorption lines of GdCl3·6H2O and its dependence on the orientation of the crystal has given the constants for the magnetic ellipsoids for the ground state and 11 excited states. Evidence is presented for identifying the first three absorption groups as transitions from 8S to 6P7/2, 6P…

Previous studies of the kinetics of dehydroxylation of kaolinite and halloysite point to first‐order reactions, in approximate conformity with the Arrhenius relation. Isothermal weight‐loss measurements have shown that the rate constants are markedly dependent on factors such as specimen size, shape, and compaction. A…

Upon depoling ceramic barium titanate, up to 9% of the domains reorient by 90°, indicating that during poling at least this percentage of the domains was permanently reoriented by 90°. Ceramic barium titanate shows a strong anelastic effect in the ferroelectric state, presumably due to domain reorientations under stre…
