摘要：

This article presents results of the study on the dependence of the structural-phase state of alloys based on Ti-12.52Al-43.08Nb system (wt.-%) on the temperature of spark plasma sintering. It has been established that spark plasma sintering of Ti-Al-Nb alloys under the temperature of 1500 °C resulted in melting the aluminum component of the mixture that, in turn, negatively affects the quality of ready products. It has also been shown that stepping up the sintering temperature from 1000 °C to 1300 °C leads to increasing volume fraction of O-phase up to 49.63 % due to rapid precipitation of O-phase from B2-phase and Ti3Al-phase. It has been revealed that intermetallic composites obtained under the temperature of 1300 °C are characterized by a dominant two-phase B2+O structure which is more suitable for strengthening sorption properties of hydrogen-storing materials based on Ti-Al-Nb. © 2021 Walter de Gruyter GmbH, Berlin/Boston, Germany.
