Abstract

This article is dedicated to the relationship search between electrotechnical materials with Сr-50%Cu composition, obtained by means of hot forging, physical properties and their microstructure generalized abstract indices based upon quantitative metallography. It is shown that there is strong correlation between these properties, material microstructure fractal dimension and degree of microstructure approach to regular one index, proposed by authors, normalized to durable particles average size, meanwhile this index calculation takes noticeably less computing resources and time than fractal dimension calculation.ю
