“…The compression parameters, i.e. temperature, deformation and strain rate, were selected based on references [18][19][20]27], where the Al-Mg-Al multi-layer material rolling process was investigated. The compression tests were conducted for the following parameters: temperature -420ºC, strain rate -0.…”

AnAlysIs of the deformAbIlIty of two-lAyer mAterIAls AZ31/eutectIcAnAlizA możliwości odksztAłcAniA plAstycznego mAteriAłu dwuwArstwowego Az31/eutektykAThe paper present the results of physical simulation of the deformation of the two-layered Az31/eutectic material using the Gleeble 3800 metallurgical processes simulator. The eutectic layer was produced on the Az31 substrate using thermochemical treatment. The specimens of Az31 alloy were heat treated in contact with aluminium powder at 445°C in a vacuum furnace. Depending on the heating time, Al-enriched surface layers with a thickness of 400, 700 and 1100 µm were fabricated on a substrate which was characterized by an eutectic structure composed of the Mg17Al12 phase and a solid solution of aluminium in magnesium. In the study, physical simulation of the fabricated two-layered specimens with a varying thickness of the eutectic layer were deformed using the plane strain compression test at various values of strain rates. The testing results have revealed that it is possible to deform the two-layered Az31/eutectic material at low strain rates and small deformation values.

“…Coarsening also occurred when MgeAleY alloys were investigated [34]. Li et al [35] reported that an addition of 1e3% Gd to an AZ31 alloy produced significant grain refinement. Liu et al [36] found that a combined addition of 1% Gd and Ca reduced the grain size of a Mge7Ale1Si alloy, but the grain size became larger after more GdeCa was added.…”

a b s t r a c tThe effect of Sm on the microstructure of a Mge3Al alloy has been investigated where it was found that the size of the primary a-Mg grains was significantly coarsened by the addition of 0.7 wt. % Sm, but dramatically refined by 2.1 wt. % Sm. It is proposed that the coarsening effect of Sm is due to a decrease in the nucleation potency of the native AleFeeCeO particles when they transform to the lower potency Al eFeeSmeCeO particles. The grain refinement observed when 2.1 wt. % Sm is added, is caused by the formation of potent Al 2 Sm nucleant particles prior to the solidification of a-Mg. The "InterdependenceTheory" was then applied to describe the nucleant selection process in the Mge3Ale2.1Sm alloy.

“…It is shown that the mechanical properties of Mg alloys could be improved remarkably by the addition of rare earth metal [3]. Therefore, Mg-rare earth alloys have received great interest from both the experiment and theory [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…Mg-Gd alloys were found to exhibit excellent strength, good creep-resistance and thermal stability [4][5]. So many investigations have been done on the Mg-Gd base alloys [6][7][8][9][10][13][14][15]. For Mg-Gd binary alloy, the precipitation sequence of the ␣ -Mg supersaturated solid solution with increasing temperature was as follows: Mg (S.S.S.S) → ␤ (D0 19 ) → ␤ (cbco) → ␤ (Mg 5 Gd f.c.c.)…”
