This paper summarizes the most important results of research dealing with the use of the magnetic spot-pole method and measurement of ultrasonic wave velocity for process control of castings made from austempered ductile, grey and vermicular-graphite irons. It describes the most important dependencies between the measured physical quantities on the specific structure of these materials, especially the content of retained austenite. It also suggests other possible developments of this control methodology.

Keywords: Magnetic structuroscopy, ultrasonic structuroscopy, austempered irons
