“…The development of ceramics with disperse-hardened binders is one of the promising ways to enhance them; for example, self-propagating high-temperature synthesis (SHS) composite materials based on Ti-Zr-C and Ti-Nb-C with Ni–Al–Co–Cr binder, where intermetallic phase grains 50–70 μm in size ( Figure 2 a,c) are precipitated during annealing. Precipitation of the intermetallic phase increases the material hardness, wear resistance and oxidation resistance [ 34 ]. Also, alloys with a hierarchical structure not only in the metallic binder, but also in the carbide grains: the so-called “STIMs” (synthetic hard tool materials), were obtained using the SHS method [ 35 , 36 ].…”

“…Он позволяет получать порошковые материалы с ультрамелкодисперсной и нанокристаллической структурами. При этом ма-лая взаимная растворимость титана и меди не является критичной, так как с помощью МЛ можно получать порошки пересыщенных твердых растворов и метастабильных фаз [15][16][17]. Интенсивная пластическая деформация порошков в условиях ШПМ приводит к формированию чередующихся наноразмерных слоевых структур, накоплению большой плотности дефектов кристаллической решетки [18], что позволяет активизировать процессы спекания либо получать готовые изделия с требуемым уровнем пористости при меньших температурах [19].…”
