摘要
The article considers the influence of the technological regimes of melting by vacuum induction and oriented crystallization on the content of alloying elements and the structure as well as the influence of the chemical composition on the structure and the phase composition of in situ composites of a Nb–Si system alloyed with titanium, hafnium, aluminum, chromium, molybdenum, tungsten, and zirconium. © 2017, Pleiades Publishing, Ltd.
