INVESTIGATION OF DIFFUSION OF ALLOYING ELEMENTS DURING THERMAL CYCLING OF MULTILAYER COMPOSITE MATERIAL MADE OF CHROME AND CARBON STEELS

Abstract

In this work the effect of five cycles of heating to a temperature of 1000 °C and three cycles of heating to a temperature of 1100 °C on the structure of multilayered composite material consisted of 100 alternating layers of 08H18 and U8 steels was investigated via the methods of microstructural analysis. It is shown that already in the initial state after rolling there was a redistribution of carbon between the layers of the material. Thermal cycling led to a partial redistribution of chromium in the material, a change in the structure and thickness of the layers.
