Page 1-69 - ... 1962, he predicted through mathematical calculations that electron pairs in a superconductive state could "tunnel" through an electrical insulator, if it is thin enough and placed between two superconductors. Superconductivity is the state in which there is no electrical resistance in certain materials when they are cooled to within a few degrees of absolute zero or minus 460°F. Josephson also believed there would be no difference in voltage across the insulator between the superconductors if...
Page 1-51 - Furthermore, it was established that these carbides are paramagnetic In the presence of austenite. the Mossbauer peak for the carbides is overshadowed In single phase materials grain size has no effect on the Mossbauer spectrum In multiphase materials the peak locations are unaffected by grain size, but quantitative evaluations are influenced Author N68-28366*1 National Aeronautics and Space Administration Lewis Research Center.
Page 1-51 - A ferromagnetic phase, thought to be pseudomartensite. has been found to exist in sensitized Type 301 Stresses generated in the matrix by morphology changes of the precipitated carbides is deemed responsible for the creation of this phase No such phase was detected in the Type 304L It was confirmed that the precipitated carbides were of the complex type Furthermore, it was established that these carbides are paramagnetic In the presence of austenite.

Page 1-51 - A relatively new research tool has been brought to bear on a relatively old problem. Mossbauer effect spectroscopy in conjunction with X-ray diffraction techniques were used to study the phenomenon of stainless steel sensitization. A ferromagnetic phase, thought to be pseudomartensite, has been found to exist in sensitized Type 301. Stresses generated in the matrix by morphology changes of the precipitated carbides is deemed responsible for the creation of this phase. No such phase was detected in...
