It is shown that electron paramagnetic resonance can be used to study the fine structure of glasses and glass enamel materials as well as to find and identify defects in glass. The spectra of paramagnetic ions (Cu2+, V4+, Ti3+, Mo5+ Mn2+, Fe3+ ) are discussed. Specific examples of the detection of these ions in sitals, in which they are introduced as surface-active additives or are present as impurities...
Results of a detailed study of continuously-cast low-alloy pipe steel metal demonstrate a significant difference in micro- and macrostructural states, including the presence and extent of equiaxed and columnar crystal areas in relation to the later stages of ladle treatment. A marked difference is also recorded in impact strength indices, hydrogen corrosion cracking resistance, and other service...
