The Divergent Beam (Kossel) X-Ray Method and Its Uses in Measuring Strain Contours in an Individual Grain of Fe-3 Weight Percent Si Transformer Sheet

Description: From Abstract: "The results showed that a variable strain distribution existed in the alloy sheet at the time it was ready for insertion into a transformer core. Small applied comprehensive and tensile loads tended to rearrange this variable strain distribution but not appreciably alter the total stored elastic energy."

Space Groups and Lattice Complexes

Description: From Abstract: "The lattice complex is to the space group what the site is to the point group - an assemblage of symmetry-related equivalent points. The Tables list site sets and lattice complexes in standard and alternate representation. The higher the symmetry of the crystal structures is, the more useful the lattice-complex approach should be on the road to the ultimate goal their classification."

The Electroslag Melting Process

Description: "This Bulletin traces the development of the electroslag melting process from its modest beginnings to the present. Important basic mechanisms such as electrochemistry, thermochemistry, and heat transport are described. Since the choice of flux is a unique parameter in the electroslag process, two chapters are developed to this subject. Electroslag melting experience for reactive metals, base metals, ferrous alloys, superalloys, and the refractory metals, both inside and outside the Bureau of M… more
