Local electron beam heat treatment of forging dies

Popis výsledku v původním jazyce

The usage of the high-energetic source electron beam can enable the repeated surface quenching of chosen areas of an engineering part surface. This treatment leads to a local hardness improvement, resulting in the local wear damage decrease during the part usage. The possibility to increase the hardness of forging dies surface (alloyed steel X37CrMoV51 (1.2343)) with the electron beam treatment was the main goal of the applied development. Such local hardness increase in the critical areas of forging dies should prolong their working time and thus decrease the frequency of their renewing. The article deals with the influence of the particular technological parameters of this treatment on the final properties of the treated areas. The electron beam surface quenching resulted in a very fine martensitic microstructure with the hardness of 800 HV. The maximum quenched depth was of 1.00 mm and 0.75 mm for the trace width of 20 mm and 40 mm, respectively. The hardness values continuously decrease from the surface to the material volume.
