    A Ti-15Mo/TiB metal-matrix composite was produced by spark plasma sintering at 1400 °C. The fractions of the elements in the initial powder mixture were 80.75 wt.% Ti, 14.25 wt.% Mo, and 5 wt.% TiB2. The initial structure of the synthesized composite was composed of bcc titanium matrix and needle-like TiB reinforcements with an average thickness of 500 ∓ 300 n

    A Ti-15Mo/TiB metal matrix composite was produced by the spark plasma sintering process at 1400 °C using a Ti-14.25 wt.% Mo-5 wt.% TiB2 powder mixture. The microstructure and mechanical properties of the composite were studied after non-isothermal rolling of specimens heated to 1000 °C to a thickness strain of ~0.

    A Ti-15Mo/TiB metal matrix composite was produced by the spark plasma sintering process at 1400°C using a Ti-14.25 wt.% Mo-5 wt.% TiB2 powder mixture. The microstructure and mechanical properties of the composite were studied after non-isothermal rolling of specimens heated to 1000°C to a thickness strain of ~0.7. Transmission and scanning electron microscopy, as well as X-ray analysis were used for microstructure examinatio

    A Ti–15Mo/TiB metal-matrix composite was obtained by the spark plasma sintering at 1400 °C; a powder mixture of Ti-14,25 (wt.) % Mo-5 (wt.) % TiB2 was used. The microstructure and mechanical properties of the composite were studied after rolling samples heated to 1000 °C to a total true strain of ~ 0,7. It was found the rolling led to considerable increase in ductility without a significant loss of strength of the composite.Металл-матричный композит Ti-15Mo/TiB был получен искровым плазменным спеканием порошковой смеси Ti — 14,25 вес. %Mo — 5 вес. % TiB2 при 1400 °C. Микроструктура и механические свойства композита были изучены после горячей прокатки при 1000 °C до истинной деформации ~0,7. Показано, что прокатка привела к значительному повышению пластичности композита без существенной потери прочностных характеристик

    Исследованы структура и механические свойства при комнатной и криогенной температурах нового среднеэнтропийного сплава Fе65(CoNi)25Cr9,5C0,5 в литом, деформированном и отожженном состояниях. Деформация осуществлялась путем холодной прокатки до 80% обжатия. Последующий отжиг привел к выделению карбидов типа M23C6.Structure and mechanical properties at room and cryogenic temperatures of a new medium-entropy Fе65 (CoNi)25Cr9.5C0.5 alloy were investigated in the as-cast, cold-worked, and annealed conditions. Deformation was carried out by cold rolling up to 80% reduction. Subsequent annealing resulted in the precipitation of M23C6 type carbides.Работа выполнена при финансовой поддержке Российского научного фонда, грант № 20-79-10093.
