Typically, amorphous RP powder was milled by using horizontal oscillatory mill consisting of hard steel balls placed in steel cells. A weight ratio of 15:1 of steel balls to RP powder, milling time periods of 0 h, 12 h, 24 h, 36 h, and 48 h and a rotation speed of 250 rotations/min were used for the milling process.

· Titanium hydride (TiH2) is one of the basic materials for titanium (Ti) powder metallurgy. A novel method was proposed to produce TiH2 from the reduction of titanium tetrachloride (TiCl4) with magnesium hydride (MgH2) in the hydrogen (H2) atmosphere. The primary approach of this process is to produce TiH2 at a low-temperature range through

Solid-State Reduction. The metal ore is crushed and then mixed with another material, usually carbon. Once the mix is complete, it’s put through a furnace to create a reaction that lowers the oxygen and carbon levels in the powder. The reduction in carbon and oxygen leaves the metal mix resembling a less-delicious sponge cake. The “sponge
