Abstract
The effect of powder processing on the microstructure and sinterability of the heavy alloy W-Ni-Cu was investigated. The heavy alloy powders were prepared by the ball milling and hydrogen reduction of metal oxide powders. As the milling time increased, the size of the powder mixture decreased and at 5 h..... More

Abstract
The effects of fabrication method on the microstructure and sinterability of W-1 wt% Y₂O₃ were analyzed. W composite powders dispersed with Y₂O₃ particles were synthesized by the ultrasonic spray pyrolysis process or the ultrasonic spray pyrolysis/polymer solution process. A dense composite was fabricated by a combination of spark plasma sintering..... More
