- Opis:
- W-1 wt% Ni (W1Ni) matrix composites reinforced with $TiB_2$ and $La_2O_3$ particles were fabricated via mechanical alloying and activated sintering methods. Powder blends with compositions of W1Ni-2 wt% TiB_2-x wt% $La_2O_3$ (x = 0.5, 1) were mechanically alloyed for 6 and 12 h. The results showed that increase in mechanical alloying duration to 12 h causes the decline of grain sizes of the W-Ni matrix to nanoscales. $TiB_2//La_2O_3$ particles have a significant effect on the density/microhardness values and wear amounts of the sintered samples.
