Abstract:
Both steel and aluminum alloys rank among the most important structural materials due to their suitable properties in various applications and low material cost. Bonding of such dissimilar materials and formation of a composite material can lead to an effective combination of steel high strength and aluminum low density and corrosion resistance. [..]

Abstract:
The corrosion resistance of aluminum-silicon (Al-Si) foundry alloys is a result of microstructure development influenced by melt treatment and solidification. As a part of the main eutectic (αAl + βSi), βSi particles are cathodic with respect to the αAl matrix enabling micro-galvanic couple formation and localized corrosion. [..]

Abstract:
The fundamental magnetic characteristics of R2Fe14B intermetallics are highly sensitive to atomic substitutions and interstitial absorption of light elements. In this work, both were combined, and the influence of the substitutions in the R-sublattice and hydrogen absorption on the magnetization of (RR’)2Fe14BHx (R is Tm or Er, and R’ is Nd) in magnetic fields up to 58T was studied.

Abstract:
This work is devoted to the study of the synthesis of various ternary intermetallic compounds based on aluminum in two alternative ways - self-propagating high-temperature synthesis (SHS) and mechanosynthesis (MS) and subsequent hot extrusion (HE) of pure aluminum powder mixtures as a matrix and the above-mentioned TIM as a hardening additive. Mechanical tensile tests showed an increase in tensile strength by 3.3 - 9.7% rel. [..]

Abstract:
Palladium membranes have a high selectivity for hydrogen, which is coupled with their temperature and mechanical stability. Such a selectivity of palladium membranes makes the membrane method the single procedure that allows one to prepare the high-purity hydrogen (no less than 99.9999 vol%) being the main energy carrier in hydrogen power engineering.
