The influence of alloying elements on the activity of dissolved carbon for welding the alloys of Cr-Mn-Mo-Ti iron-based
The aim of this work was to investigate the distribution of the TiC phase in the alloys of Cr-Mn-Mo-Ti iron-based at various ways of surfacing. Experimental studies were performed single-layer welding or flux-cored system Cr-Mn-Mo-Ti iron-based feed additives in de-energized the head part of the weld pool with the study of the chemical composition and metallographic tests. It is established that the application of hardfacing flux cored wire with exogenous input of carbides in the weld pool contributes to a more uniform distribution of the carbide phase in the volume of metal in comparison with endogenous entry of carbides. The increased content of Mn and Cr in the weld metal and reduce the activity of carbon as a carbide of the element.. the increase in the number of TiC phase increases internal warmth of weld metal at its exogenous input.
