Abstract


The influence of thermodeformation modes of prototype technological schemes of strengthening processing, including high-temperature thermomechanical processing, on structure and mechanical properties of steel 38ХН3МФА is considered. It is shown that the setting ratio increase from 2,0 to 6,6 completely excludes dendritic structure formation in the sample, raises yield stress by 20 per cent and strength limit by 11 per cent. The tempering temperature influence on mechanical properties depends upon a heating method - furnace or induction.

Keywords
