Abstract:

The investigation, devoted to the study of phase and structural changes during hardening and tempering of alloy VT18, was carried out on rods obtained by extrusion. The rods were cut into blanks and heat-treated. Samples were cut from these blanks in order to study the microstructure and for X-ray and dilatometric analyses. The X-ray analysis was done on the URS-50IM diffractometer and in the RKD and KROS chambers in copper and nickel radiation. Dilatograms were obtained on the UVD vacuum dilatometer. The electron-microscope study was carried out on the UEMV-100 microscope, using the method of replicas.
