Studies of the transition zone in steel - chromium cast iron bimetallic casting

In this work authors presented the results of transition zone studies on steel - cast iron interface in bimetallic casting. During the investigations cylindrical castings with different diameter were prepared of cast iron with steel rods placed in the center. From each bimetallic casting a microsection was prepared for microhardness tests and metalographic analysis, consisting of transition zone measurement, point and linear analysis as well as quantitative analysis.
