Abstract

Innovative idea of the device for detecting microstructure changes, concept and construction was carried out and controlled by authors of this article in cooperation with Slovenian industry. Since the electrical resistance is one of the most structurally sensitive properties of the materials, we used its measurement to detect microstructural changes caused by phase transformations or chemical reactions. Until now, we analyzed the phase transitions in rapidly solidified alloys of copper and aluminum, nickel and nickel alloys, and several types of steel made by Slovenian steel producers.
