Abstract
In a method for the measurement of the distribution of the inclusions in a slab by electron beam irradiation, an electron beam of relatively large diameter is irradiated onto a relatively large specimen of the slab and a spectrum analysis of the characteristic X-rays is effected by using planar analyzing crystals, in order to obtain the data of the two-dimensional distribution of the elements of the inclusions in the surface of the specimen.
