“…The influence of alloying agents (AAs) on the composition/morphology of complex borides was explored by Takagi et al [30][31][32][33]38]. In this work, we attempted to introduce AAs (such as Cr 2 O 3 , V 2 O 5 , MnO 2 ) into green mixtures, prior to combustion synthesis.…”

“…An increase in α and β was found to have only slight influence on U: it increased from 4 to 5 cm/s. It is well known that complete melting of system components is a prerequisite for good sensitivity of the process to gravity forces [13][14][15][16]31]. Figure 14 shows the burning velocity (U), material loss ( sput ), and product yield ( ingot ) as a function of a/g.…”

This work aims to establish a scientific and engineering background in the production of cast multicomponent alloys and metal-martix composite (MMCs) via Self-Propagating High Temperature Synthesis (SHS, combustion synthesis) which is a novel process technique regarding fast and low-cost production ability. We carried out the search for reactive systems and process parameters that would ensure preparation of cast multicomponent materials in a single process. The principles and methods of the SHS thermite-type reaction processes have been investigated under high-gravity values applying loads up to 1000 g with special centrifuge set-up. In this way we expected to improve the yield of target product, remove gaseous byproducts, diminish the grain size in the product, and make product composition more uniform. The obtained results can be expected to make a theoretical background for industrial-scale manufacturing of heat-resistant intermetallic alloys, master alloys, catalysts, MMCs etc.

Самораспространяющийся высокотемпературный синтез марки ПА4 в количестве 5 % в СВСсмесь позво ляет на порядок уменьшить размер синтезируе мых частиц карбидной фазы TiС с 2-4 до 0,17-0,35 мкм, т. е. достичь уровня ультрадисперсной армирующей фазы в литом композите Al-10%TiС. А замена 30 % металлического титана в СВСсмеси на галоидную титансодержащую соль Na 2 TiF 6 дает возможность синтезировать частицы TiC разме ром менее 100 нм, т. е. достичь уровня наноди сперсной армирующей фазы в этом композите.

“…3): from 2 to 6.2 cm/s for com position II and from 2 to 8.2 cm/s for composition III. The most intense increase in the front propagation rate (by more than a factor of 4) was observed in a range of values a = 10-150 g. The increase in the mag nitude of U c is caused by the forced filtration of a high temperature melt into the initial mixture [12][13][14].…”

Cast Intermetallic Alloys by SHS Under High Gravity

Abstract: Pilot-scale series of cast Ti-Al, Ti-Al-Nb, (Ni, Co, Mn)Al x , Ni-Cr-Al-Si-C, and Co-V-Al-Si-C alloys were produced by thermit-type SHS under high gravity for their potential use as heat-resistant materials, master alloys, precursors for catalysts, etc.
