The purpose of this article is to study the formation of intermetallic compounds (IMCs) at the interface of Al/Cu bimetal produced by compound casting of molten Al in solid copper tubes. The mechanism of the intermetallic compounds formations at the interface, the effects of molten aluminum pouring temperature and solid copper tubes preheating tempreture, were investigated on the IMCs type...
This article deals with a method of obtaining materials in the Ti-Al system. Research was carried out in accordance with the phase diagram of the system state. It was established, that both single-phase and multiphase systems, containing finely dispersed intermetallic compositions of phases Ti3Al, TiAl and TiAl3, are formed. Additionally, it was found that the pure finely dispersed (coherent-sc...
The results of a thorough structural study of crystalline intermetallic compounds within the Al-Li-(Cu,Mg,Zn) system are given. Characteristic morphologies of these ternary or quaternary phases are exhibited by concentrated alloys or large single crystals. Typical X-ray powder diffraction data, selected area electron diffraction patterns and high resolution electron microscopy images are shown,...
Intrinsically chiral surfaces of intermetallic compounds are shown to be novel materials for enantioselective processes. Their advantage is the significantly higher thermal and chemical stability, and therefore their extended application range for catalyzed chiral reactions compared to surfaces templated with chiral molecular modifiers or auxiliaries. On the Pd1 -terminated PdGa(111) surface, r...
