“…In addition, the additions of Y to the Mg-Zn-Zr alloy result an increase in the volume fraction of the interdendritic compounds [3].SEM observations showed that the microstructure of base alloy consists of solid solution structure α-Mg grains, surrounded by intermetallic phase on grain boundaries. The EDS results for base alloy showed that the matrix consists of magnesium and a small amount of zirconium and binary phase Mg 3 (Nd, Gd) [18].SEM observation and EDS results of EV31A +1 Y alloy are shown in Fig ( 2). It showed that the EV31A +1 Y alloy consisted of two phases, the α-Mg matrix and intermetallic compound contain Mg,Gd,Nd,Zn,Zr,Y which means that Y combined with the intermetallic phase, thus continuously distributed along the grain boundaries.…”

The effect of the rare earth (RE) element Y on the microstructure and hardness of (Mg–0.5Zn–0.5Zr–2.8Nd –1.5Gd) wt% Mg alloy investigated. 1 wt. % Y was added and compared with the base alloy. The microstructure results show the refinement of the grain by the addition of Y and the grains became smaller about 31.8 % and the volume fraction was increases 11.1% %, which led to the increment of hardness from 48.33 HV (as-cast EV31A) to 53.71 HV (as-cast EV31A +1 Y). Energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) results showed that the base alloy mainly contained α-Mg matrix and Mg-(Nd, Gd) as a second phase crystallized along the grain boundaries and addition of (Y) yttrium resulted in the formation of the new phase, Mg-Zn-Y-phase was found as a new ternary phase, where Y combined with the original second phase.

The results of the microstructure investigations of the pure Al and AlMg5 alloy and pure Cu and CuFe2 alloy after the application of severe plastic deformation implemented by rolling with the cyclic movement of the rolls are presented in this paper. The rolling with the cyclic movement of the rolls was carried out at values: the rolling rate v = 1 rpm, the frequency of rolls movement f = 1 Hz, the amplitude of rolls movement A = 1.6 mm. Maximal values of rolling reduction at 6 passes was ε h = 80%. The structure of the these materials was analyzed using scanning transmission electron microscope. The quantitative studies of the substructure was performed with MET-ILO software, on the basis of images acquired on scanning transmission electron microscope. Performed substructure investigations showed that using the rolling with the cyclic movement of the rolls method can refine the microstructure of these materials to the ultrafine scale.
