The primary objective of this investigation is to examine the impact of adding (Ge) to the Ti12Mo5Ta alloy on its compressive strength, hardness, and elastic modulus. A Ti-Mo-Ta alloy with an 83% Ti, 12% Mo, and 5% Ta composition was synthesized by powder metallurgy, with the inclusion of Ge. The mixing procedure lasted for a duration of 5 hours, with a compacting pressure of 800MPa applied to create a disk sample. After the compaction step, the samples were sintered by gradually increasing the temperature to 950 ºC at a rate of 10 ˚C/min, which took a total of 7 hours. The addition of (Ge) is done in different weight percentages, ranging from 0.5% to 5%.The impact of (Ge) was examined using X-ray diffraction. The addition of 0.5% to 5% (Ge) enhances the compressive strength of the Ti12Mo5Ta alloy. Similarly, the macro hardness of the alloy increases with higher Ge content.Conversely the inclusion of 0.5% to 5% (Ge) causes a decrease in the elastic modulus of the Ti12Mo5Ta alloy.
