Opis:: In this study, we examined the effect of Ga-doping and mechanical alloying in MgB₂ on microstructural and phase evolution. A comparison was made between in-situ and ex-situ processed Mg-B-Ga samples. Densification was markedly improved by ex-situ sintering of ball-milled MgB₂+Ga. The Ga-doping and ball-milling prior to sintering resulted in the formation of impurity phases such as MgO, Ga₅Mg₂ and Ga₂O₃. Lattice parameter of MgB₂ increased with increasing ball-milling duration as well as by Ga-doping.

Opis:: In the present work, we have examined the effect of Ti on the properties of Fe-Y₂O₃ alloys. The result showed that the addition of Ti was effective for improving mechanical properties. This is due to the reduction of oxides by Ti during mechanical alloying and hot-consolidation. In particular, iron oxides are effectively reduced by the addition of Ti. Compared to the pristine Fe-Y₂O₃ alloys, titanium-added alloys exhibited fine and uniform microstructures, resulting in at least 60% higher tensile strength.
