Corrosion hydrogen weight gains were studied for four zirconium base binary systems: Zr-Fe, Zr-Cr, Zr-V and Zr-Sb. Data on twenty compositions for exposures of up to 3000 hours in water at 360 C and in steam at 400 C and 482 C showed three alloys exhibiting less hydrogen weight gain than by Zircaloy-2. The various int…
Balance studies were conducted to investigate the sodium requirement for wether lambs when a diet considered low in potassium was fed. In this study purified diets were fed which supplied 30.5 mEq. of potassium and 4.0, 44.0 or 129.0 mEq. of sodium daily. The balance data suggest that the daily sodium requirement for…
The paramagnetic resonance spectrum of the ground state of ${\mathrm{Cr}}^{3+}$ in Sn${\mathrm{O}}_{2}$ (cassiterite) was studied at 23.5 and 34.4 kMc/sec. The derived constants of the spin Hamiltonian for the magnetic $Z$ axis coinciding with the crystal $c$ axis are: $|g|=1.975$, $D=+17.3$ kMc/sec, $|E|=8.44$ kMc/se…
structure consists of a three-dimensional assemblage of distorted AsO 4 tetrahedra, CuO 4 (OH) 2 tetragonal bipyramids, and CaO 7 (OH) square antiprisms, sharing corners and edges. The possible significance of the two types of bond lengths in the AsO 4 group is discussed.

An apparatus which applies a cyclic load to a square of fabric along the warp or weft direction and a simultaneous constant load in the orthogonal direction has been constructed for use in investigating the relationships between stress and strain when a fabric is subjected to repeated stressing in two directions. Expe…
The magnetic properties and cation distributions of ferrite-chromite series of nickle and cobalt are investigated. Although the magnetic moments at absolute zero temperature are well explained by simple Néel model as far as the series remain inverse spinel structure, they begin to deviate significantly from the values…

The possibility of performing magnetic resonance experiments in substances with spiral spin structures is studied. Particular attention is paid to the variation of spin arrangement and spin-wave spectrum with an applied magnetic field in the plane of the spiral. Perturbation techniques give resonance frequencies for s…
The magnetocrystalline anisotropy of magnetite has been measured by the torque method between 4.2 and 110\ifmmode^\circ\else\textdegree\fi{}K. The anisotropy energy of the orthorhombic phase which exists below 114.5\ifmmode^\circ\else\textdegree\fi{}K is represented by the formula ${E}_{a}={K}_{a}{{\ensuremath{\alpha}…
Synthetic single crystals were grown by the flux method. It was confirmed that the weak ferromagnetic moment appears only when the spins lie in the (111) plane. Contrary to the case of polycrystallines specimens, recovery of the residual magnetization or the memory phenomenon is not observed. It was found, below the t…
Abstract The phase transition of potassium thiocyanate has been investigated by the X-ray diffraction. It was confirmed that it is an order-disorder type transition with regard to the orientation of the thiocyanate ions. The temperature dependence of the ordering and the anomalous volume expansion near the transition…
LiAl 5 O 8 exists in many forms. The equilibrium high‐temperature form (I) has a spinel structure. It undergoes a first‐order reconstructive transformation at 1295°× 5°C to an equilibrium low‐temperature form (II) with primitive cubic symmetry, the unit edge changing from a 0 = 7.921 A (I) to a 0 = 7.907 A (II). In ad…
The melting and crystallization of tetragonal phosphorus pentoxide has been investigated by the use of a microscopic technique. Superheating of about 50° above the melting temperature was possible. Melting was heterogeneous and began only at free surfaces or grain boundaries but never within a crystal. At a supercool…
An accurate electrochemical technique for the removal of extremely thin (10–1000 Å) uniform layers of metal from a tungsten target has been developed analogous to that used previously for range studies in aluminum. This technique has been used to obtain the range distributions of Xe 133 and Ar 41 ions in rolled tungst…

Thermal‐expansion measurements were made in an air atmosphere to 2200°C on polycrystalline single‐phase ceramic oxides. Specimens were fabricated by hot‐pressing, slip casting, and isostatic pressing. Magnesium oxide was tested in both air and argon; calcium oxide as well as magnesium aluminate and aluminum oxide spec…
Crystallographic analyses of dislocation networks in annealed b.c.c. iron observed in the electron microscope have been carried out by applying the kinematical theory of electron diffraction contrast at dislocations and Frank's formula for determining the dislocation content of a grain boundary from a crystallographic…
