Abstract
A method of producing a high-density article is presented comprising selecting one or more primary tungsten-containing constituents with densities greater than 10.0 g/cc and one or more secondary constituents with densities less than 10.0 g/cc, co-milling the mixture of constituents in a high-energy mill to obtain mechanical alloying effects, then processing the resulting powder product by conventional powder metallurgy to produce an article with bulk density greater than 9.0 g/cc.
