摘要：
The results of investigation of the surface structure-base transformation of iron specimens subjected to carbonization by the electrospark method and heating in the temperature range of 20-800 degrees C are given. It is known that, after electrospark alloying with graphite, a surface layer consisting of mainly austenite and cementite forms with a carbon content in gamma-Fe. The quantity of the austenite reduces with heating, and, at 300 degrees C, it fully turns into a ferrite-cementite mixture (perlite). The heating of the specimens reduces the value of the microstresses, and the diffraction lines narrow down coming nearer to the annealed armco-iron values.
