In this paper, the electronic structure and magnetic properties of ternary intermetallics HoNiZ series (Z = Ga, Si, Al) is studied using LSDA+U first-principles method. An analysis densities states in compounds HoNiGa, HoNiSi, HoNiAl with accounting for correlations performed.

due to good biocompatibility, corrosion and mechanical properties, magnesium (mg) is considered promising degradable material for orthopedic applications. in this work, mg-mgznx (x= 1, 2, 3 and 4) nanocomposites scaffolds with different porosities were synthesized via powder metallurgy method. the microstructure, composition, in vitro corrosion and mechanical properties of porous magnesium-zinc...

This work presents the results of an investigation into influence beam offset on structure and mechanical properties electron-beam-welded joints between Ti6Al4V Al6082-T6 alloys. The experimental procedure involved use specific technological conditions: accelerating voltage 60 kV, electron current 35 mA, a specimen motion speed 10 mm/s, 0.5 mm towards both alloys, as well welding without offset...
