Copper-zirconium alloys with high conductivity were produced using powder metallurgy. Two-steps manufacturing process, containing mechanical alloying followed by hot pressing, was applied in achieving improved and physical properties of Cu-Zr alloy. In this paper, the influence boron on studied Cu-1Zr (wt.%) Cu-1.1Zr-0.3B systems. Scanning electron microscopy, laser nanoparticle sizer, computed...

This article is devoted to the study of initial phase obtaining alloy 1420, namely, a primary material with desired chemical composition. The effect alloying magnesium, zirconium and lithium on strength properties material. In work, following materials were used obtain cast aluminum Al-Mg-Zr-Li system: technical purity A0 or A5, magnesium Mg95, LE-1, E100, aluminum-zirconium ligature AlZr5, alu...

Titanium and Zircaloy-4 dissimilar alloys were brazed with a zirconium-titanium-copper-nickel amorphous filler alloy, the resulting joint structures as well their corrosion properties examined. The microstructure of joints was investigated according to brazing holding time at 850 °C, property analyzed by potentiodynamic polarization. During brazing, produced diffusion-induced isothermal solidif...

Tensile–creep experiments were conducted in the temperature range 100–200 C and stress range 20–83 MPa for a series of magnesium–zinc–yttrium (Mg-Zn-Y) and mangnesium-zinc–zirconium (Mg-ZnZr) alloys ranging from 0 to 5.4 wt% Zn, 0 to 3 wt% Y, and 0 to 0.6 wt.% Zr. The greatest tensile– creep resistance was exhibited by an Mg–4.1Zn–0.2Y alloy. The room-temperature yield strength increased with i...

Zinc and zirconium were selected as the alloying elements in biodegradable magnesium alloys, considering their strengthening effect and good biocompatibility. The degradation rate, hydrogen evolution, ion release, surface layer and in vitro cytotoxicity of two Mg-Zn-Zr alloys, i.e. ZK30 and ZK60, and a WE-type alloy (Mg-Y-RE-Zr) were investigated by means of long-term static immersion testing i...
