“…In recent years, Mg-Y-Zn alloys have received considerable attention due to their excellent mechanical properties and unique microstructures [11][12][13][14][15][16][17][18][19][20]. In particular, various novel lamellar structure of long-period stacking order (LPSO) phases have been observed, including 6H, 10H, 14H, 18R and 24R [21][22][23][24][25][26][27][28][29][30][31].…”

“…After an initial work in 2003, the IFIMAT-LNESS collaboration has concentrated the attention on the commercial alloys WE43, WE54 (Mg-Y-Nd) and EV31(Mg-Gd-Nd). [13,20,21,24,25]. In the first of these studies [13] has been shown that the evolution of the positron lifetimes is strictly correlated with the changes in hardness, which are enhanced and accelerated by plastic deformation prior to heating at 250°C (see Figure 9).…”

The extensive experimental work on age hardening of Al‐ and Mg‐based alloys, performed by the associated groups at IFIMAT (UNCentro, Argentina) and at LNESS (Politecnico di Milano, Italy) in recent years, is discussed here in a comprehensive way, with attention to experimental procedures and to results of general validity. For Al‐based alloys, the established knowledge regarding the different action of Zn, Cu, Mg and Ag in the formation of vacancy‐solute clusters is presented. For Mg‐based alloys, the limits of positron annihilation spectroscopy are discussed on the basis of experience in progress. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…However, the selection rules of microalloying elements remain empirical, which will limit the promotion of the strengthening effect on the product. Previous experimental investigations [9][10][11][12][13] can provide tentative and/or qualitative results on the relation between the structure evolution of hardening precipitates and thermal treatment process in Mg-RE alloys, which are of great importance but not sufficient in quantitative designing of new magnesium alloys with higher strength.…”

The Mg-Y-Zr system was studied via experimental investigation and thermodynamic modeling. Four diffusion couples and four key alloys of the Mg-Y-Zr system at 500°C were prepared. The phase relations of the Mg-Y-Zr system were investigated by means of X-ray diffraction, scanning electron microscopy, and electron probe microanalysis. No ternary compound was found at 500°C. The solubility of (aZr) in the Mg-Y intermetallics, i.e., Mg 24 Y 5 , Mg 2 Y and MgY, was determined to be negligible. The differential scanning calorimetry measurement was performed on the Mg-Y-Zr alloys to obtain the phase transition temperature. The present thermodynamic calculations of the Mg-Y-Zr system matched well with the experimental data. The presently established Mg-Y-Zr phase diagram can offer a better understanding of the recent processing technique of creep-resistant magnesium alloys.
