Abstract
The influence of the temperature of heating for drop-forging on the fine structure of the ferrite of powder steel Kh17 is investigated. On the basis of structural characteristics obtained from different drop-forging sites by means of harmonic analysis, substantial differences in the degree of structural defectiveness in the crystal lattice between the outer faces and an internal layer of the samples has been established. The highest degree of structural defectiveness is found in the structure of the outer faces following heating for drop-forging to 1050 °C while a uniform structure throughout the drop-forging volume is created following heating to 1100 °C.
