Mg-2Sn, Mg-10Gd-2Y-0.5Zr, Mg-6Zn-0.7Zr Alloy

Alloy name: Mg-2Sn, Mg-10Gd-2Y-0.5Zr, Mg-6Zn-0.7Zr
Diagram No.: 857
Type of diagram: TTT
Chemical composition in weight %: Mg-2Sn, Mg-10Gd-2Y-0.5Zr, Mg-6Zn-0.7Zr
Alloy group: Magnesium-based alloys
Note: Calculated TTT diagrams of three magnesium alloys: (a) Mg-2Sn, (b) Mg-10Gd-2Y-0.5Zr, and (c) Mg-6Zn-0.7Zr.
A simple TTT diagram is shown for a Mg-2Sn (wt%) alloy, Fig. (a). In this case the only competing phase is the stable Mg2Sn phase. However, for other alloys, multiple phases will compete, some being stable phases while others are metastable. A calculation for a VW102 alloy with a composition Mg-10Gd-2Y- 0.5Zr (wt%) shows multiple phases, Fig. (b). The stable phase is the Gd-rich Mg5Re, however, as mentioned in section, Mg7Re is the hardening phase and the one with the fastest transformation rates. It is further noted that TTT curves are also calculated for the Mg12Re, Mg41Re5 and Mg24Re5 phases. These are also metastable and do not appear in an equilibrium calculation. The reason for the Mg12Re, Mg41Re5 and Mg24Re5 phases appearing in the TTT calculations is because of the high relative stability of the various MgxREy structures in Mg-RE binaries. The stabilities of these phases have been assessed from the ternary phase diagrams of Mg and Rare Earth elements, where there is considerable solubility of the binary compounds into the ternary systems.
