Abstract

The secondary carbide particles in nonledeburitic high-speed steel has been investigated. It was found that employing the scanning electron microscopy was indispensable stage of the stereological assessment of the carbide phase in this steel. The M33C6 type carbides precipitated while tempering have been characterized by area fraction, mean size (mean area of plane section), size distributions, mean shape factor and shape factor distribution. Owing to longer time of austenitizing, area fraction and mean size of the secondary carbides increased, which were accompanied by more homogeneous distribution of these particles in the matrix.
