to develop new magnesium casting alloys. The temperatures for T6 heat treatment were selected based on the hardness and electrical conductivity measurements. The hot tearing susceptibility of the alloys... contributes to high alloy casting properties [22]. The T4 and T6 heat treatments can be applied to the Mg-Zn-Y alloys. The heat treatment for alloys with high Y and low Zn contents and LPSO phase......

be now prepared directly by the solidification process[10-11]. For the alloys with the angle equal to 0?-5?, the effects of heat treatment on magnetic properties have been studied, and these magnets, finally with 143.3 kJ/m3, directly prepared by directional solidification and heat treatment, are more ductile than the sintered ones with the same compositions. However, the macroscopic c-axis texture......

at the interface is a major challenge. The extended heat-treatment made the perovskite change from dark brown to right yellow due to ZnO induced proton-transfer reactions at the ZnO/perovskite interface, leading..., the inverted planar PSCs have drawn tremendous attention and show high efficiency close to that of the meso-PSCs [22-24]. Many efforts in device fabrication, composition engineering, post-treatment......
