Features of combustion in the Mo-Si-B system: Part 2. Effect of mechanical activationAllerton Press - Tập 56 - Trang 307-312 - 2015
E. I. Patsera, V. V. Kurbatkina, E. A. Levashov, N. A. Kochetov
This study is devoted to investigating the effect of mechanical activation (MA) on the kinetics and combustion mechanism of a reaction mixture in the Mo-Si-B ternary system, as well as ceramic material production by the self-propagating high-temperature synthesis (SHS) method. Elemental molybdenum, silicon, and boron powders are used as the initial components. The MA was carried out in a planetary...... hiện toàn bộ
A Novel Developed Grain Refiner (Al–Y–B Master Alloys) Using Yttrium and KBF4 PowdersAllerton Press - Tập 59 - Trang 50-55 - 2018
Rongfu Xu, Qingzhou Sun, Zhigang Wang, Yong Xu, Wencheng Ren
The present work aims to report and discuss the development of a novel grain refiner (Al–Y–B master alloys) focusing on the characterization of the phenomena that exist during their production. Al–Y–B master alloy is produced by the combined employment of yttrium and boron, instead of yttrium or boron individually. It is discovered as a highly effective grain refiner for inoculating the grain size...... hiện toàn bộ
Development of nanoparticle-reinforced alumocomposites for rocket-space engineeringAllerton Press - Tập 56 - Trang 325-328 - 2015
V. I. Kostikov, L. E. Agureev, Zh. V. Eremeeva
Some results of the development of a composite material based on sintered aluminum powder containing small additives of Al2O3 nanoparticles produced by the plasma-chemical method are described. The reasons for using small nanoparticle concentrations from the point of view of the role of interphase layer, Orowan hardening mechanism, etc., are given. Some properties and microstructure of produced al...... hiện toàn bộ
Self-Propagating High-Temperature Synthesis of a Thin-Layer CuO–B–Glass SystemAllerton Press - Tập 60 - Trang 426-433 - 2019
A. M. Shulpekov, O. V. Lapshin
Experimental studies are performed and mathematical models of the wave synthesis and thermal explosion in a thin-layer CuO–B–glass system are constructed. It is established that the propagation of the combustion front occurs in a multisource mode and its rate depends on the reaction layer thickness (d) according to the parabolic law with a maximum at d = 4 × 10–4 m. An increase in the reaction lay...... hiện toàn bộ
Studies on dissolution kinetics of dolime in electrothermal magnesium slagAllerton Press - Tập 57 - Trang 287-295 - 2016
Krishna Kumar, Navneet Singh Randhawa, Kalpataru Gharami, D. C. Sau, Manoj Kumar
The electrothermal process of magnesium metal production is a promising route, where large sized internally heated reactor is used for magnesium production resulting in less energy and labour intensive and high space-time yield process. However, the dissolution behavior of dolime in the electrothermal slag has been found critical for the process optimization. In this paper, the dissolution kinetic...... hiện toàn bộ
