INSTRUMENT FOR DETECTING DEFECTS IN THE SUBSURFACE LAYER OF A NONMAGNETIC METAL.

Abstract

The paper describes an instrument which permits the detection of microinhomogeneities or disturbances of continuity in the surface or subsurface layer of a nonmagnetic metal, i.e., surface and subsurface cracks, cavities, nonmetallic inclusions, and others. With appropriate calibration the instrument can also be used for determining the intensity of workhardening of the surface of a nonmagnetic metal. The measurement method is based on the determination of the anisotropy of electrical resistance in two mutually perpendicular directions passing through a given point of the metal. (Author)
