摘要：
The present invention relates to a method of making ultrafine WC—Co alloys from a well dispersed mixture of fine and non-agglomerated WC and Co powders, wherein the Co powders have a narrow grain size distribution wherein at least 80% of the grains have sizes in the interval x+0.2x with the interval of variation of 0.4x is not smaller than 0.1 um, and a carbon content of approximately the amount necessary to provide eta phase formation.
