X-Ray Studies on a Silver Bearing

Abstract

By means of X-ray analysis, a silver bearing of unknown. origin was investigated. The method of manufacture was not determined by any metallographic means, but the X-ray analysis could show that it was an electrc-plated one. Further the temperature of annealing of that specimen was determined by the X-ray methods obtaining the following results 1) by the Lane photographic method: the upper limit of annealing temperature, 340°C; 2) by the back reflection method: the upper limit of annealing temperature, 320°C and the lower limit 300°C.
