Opis:: The results of some mechanical properties of four Mg-5Al-xRE-0.4Mn (x=1–5) alloys are presented. The microstructure of experimental alloys consisted of an σ-Mg phase and an α+γ semi-divorced eutectic, Al₁₁ RE₃ phase and an Al₁₀ RE₂ Mn₇ intermetallic compound. For gravity casting in metal mould alloys, Brinell hardness, impact strength, tensile and compression properties at ambient temperature were determined. The performed mechanical tests allowed the author to determine the proportional influence of the mass fraction of rare earth elements in the alloys on their tensile strength, yield strength, compression strength and Brinell hardness. The impact strength of the alloys slightly decreases with a rise in the rare earth elements mass fraction.

Opis:: Magnesium alloy with 5 wt% Al, 0.35 wt% Mn and 5 wt% rare earth elements (RE) was prepared and gravity cast into a sand mould. Microstructure investigations were conducted. Analyses of the Mg-Al-RE alloy microstructure were carried out by light microscopy, scanning electron microscopy and the XRD technique. In the as-cast condition, the alloy was composed of α-Mg, Al11RE3 and Al10RE2Mn7 intermetallic phases. Additionally, due to non-equilibrium solidification conditions, an Al2RE intermetallic phase was revealed.

Opis:: The results of microstructure investigations of an experimental magnesium matrix composite reinforced with Ti particles are presented. The experimental Mg-5Al-5RE magnesium alloy was used as the matrix alloy. The examined composite was reinforced with 30 wt% titanium spherical particles. The investigated material was obtained by the stir-casting method. The microstructure of the fabricated composite was characterized by a uniform arrangement of the Ti particles within the magnesium matrix. No new phases (created due to reaction between the matrix and Ti particles) were revealed by XRD techniques.
