Analysis of Electron-Optical Studies of Experimental Alloys of Fe-W and Ferrotungsten

Analysis of electron-optical studies of experimental alloys of Fe-W and ferrotungsten

In this paper the experimental alloys of the Fe-W, which melted with refractory W - Ni - Fe scrap, compared with the standardized grade ferrotungsten ΦB 70. The comparative analysis of the microstructure, phase and chemical composition of the experimental alloys. Investigated the number of non-metallic impurities, the number of which is within the nominated GOST 17293-93. It is proposed to re-use as a substitute for ferrotungsten alloys for the manufacture high tungsten special materials based on iron.
