A method for producing a reinforced alloy powder containing a metal matrix in which crystalline oxide particles are dispersed, including: (i) providing a powder mixture including a parent metal powder including a master alloy for forming the metal matrix and an additional powder including an intermediate; (ii) milling the powder mixture by a mechanical synthesis process to make a precursor powder; and (iii) subjecting the precursor powder to a thermal plasma generated by a plasma torch including a plasma gas. The master alloy is iron-based, nickel-based, or aluminum-based. The intermediate is at least one of YFe, YO, FeO, FeTi, FeCrWTi, TiH, TiO, AlO, HfO, SiO, ZrO, ThO, and MgO. In (iii), the precursor powder is injected into the plasma torch at a flow rate of 10-30 g/min, a power of the plasma torch is 20-40 kW, and a pressure in a reaction chamber of the plasma torch is 25-100 kPa.
