The Waves

Three experiments are described in which the relative motion of media or structures causes nonreciprocal effects of first order in ν/c. The first two experiments deal respectively with the Fresnel effect due to the motion of a normal dielectric and the electron drift in the plasma of a glow discharge. The third experiment is a microwave analogon to the historical experiments of Harress, Pogany and Sagnac. To our knowledge these are the first investigations of the well-known effects under conditions where the transverse dimensions of the waves are comparable to the wave length. Under such conditions the nonreciprocal effects when expressed in fringe shifts (or phase angle) remain small. They could, however, be detected after the development of an elaborate microwave interferometry which could resolve fringe shifts down to the order of 10-6.

Abstract Carburization is a common method of hardening steel surfaces to be wear-resistant for a wide range of mechanical processes. One critical characteristic of the carburization process is the increase in carbon content that leads to the formation of martensite in the surface layer. Combustion and spark-OES are two common methods for determination of carbon in steels. However, these techniques do not effectively separate carbon from near surface contaminants, carburized layers, and base material composition. Careful consideration of glow discharge spectroscopy as a method of precisely characterizing carbon concentration in surface layers as part of a production process should be evaluated in terms of how the resulting data align with other common analytical and metallurgical measurements. When used together, glow discharge spectroscopy, optical microscopy, and microhardness testing are all useful, complementary techniques for characterizing the elemental composition, visually observable changes in material composition, and changes in surface hardness throughout the hardened case, respectively. Close agreement between related measurements can be used to support the use of each of these techniques as part of a strong quality program for heat treatment facilities.
