Only some from series of non-destructive testing methods of material defects are employed for measurement of structural parameters of materials. The principle of acoustic and magnetic structuroscopy of cast irons and steel is explained. The examples of exploitation and equipment are described. At least two methods must be used simultaneously for strength and heat resistance measurement of composites, powder metallurgy products and cast irons. Development of this combined structuroscopy of cast irons. The equipment TELIT 3 was developed for evaluation of cast iron quality at critical sites of complicated castings (cylinder blocks of transport engines). The direction of furher research was indicated – exploitation of magnetic excited acoustic wave and combined structuroscopy of thin composite layers.
