The application of statistical methods to the study of technical steels is described and a statistical amplitude distribution function for the magnetization discontinuities is presented, making use of the correlation between the amplitudes observed and the structure of the material. It is shown by experimental measurements that the optically measured grain size distribution of fine-grain low-carbon steel correlates closely over a wide range with the distribution of the pulse heights measured. The results of previously performed measurements have been investigated statistically using a multichannel analyser, and these pulses are shown to obey Weibull's distribution. The physical characteristics of the distribution function of the magnetic discontinuities and its computed parameters are discussed.
