Abstract Eutectic NiAl-(Cr,Mo) composites are promising high temperature materials due to their high melting point, excellent oxidation behavior and low density. To enhance the strength, hardness and fracture toughness, high cooling rates are beneficial to obtain a fine cellular-lamellar microstructure. This can be provided by the additive process of selective electron beam melting. The very high temperature gradient achieved in this process leads to the formation of the finest microstructure that has ever been reported for NiAl-(Cr,Mo) in-situ composites. A very high hardness and fracture toughening mechanisms were observed. This represents a feasibility study towards additive manufacturing of eutectic NiAl-(Cr,Mo) in-situ composites by selective electron beam melting.

Microstructure Of The Material

The results of the analysis of works related to the formation of surface microgeometry in the process of selective electron-beam melting are presented, and the physical model of this process is refined. The developing additive technology of selective electron-beam alloying and the directions in which its research is carried out, in particular, the analysis of the metallurgical process, the formation of the microstructure of the material, the formation of microstructure defects, are described. The roughness of the surface of products obtained by the SEBM technology, as well as the microgeometry of surfaces and the mechanisms of its formation, depending on various parameters of the process, are considered.
