Claim 0:
1. A method of manufacturing a composite powder, the method comprising:
milling a metal powder until the metal particles are equiaxed in shape and have reached a predetermined saturation hardness value, creating a hardened metal powder;
milling a mixture of the hardened metal powder and a predetermined volume percent (vol %) of ceramic powder microparticles until the ceramic microparticles are uniformly distributed within the metal particles and a particle size distribution has a single peak to composite powder; and
degassing the composite powder, to remove hydrogen to a level lower than a predetermined level of hydrogen measured in ppm without causing the sieved composite powder to sinter,
wherein the degassed composite powder has a flowability flow time, as measured by a Hall flowmeter, in a range greater than or equal to 80 s per 50 g and less than or equal to 120 s per 50 g.
