Effect of deformation on $ ThO_{2} $ particle morphology in W-1 Wt Pct $ ThO_{2} $ materials
Abstract The distribution and deformation characteristics of $ ThO_{2} $ particles during processing from powder to wire have been investigated in a W-1 wt pct $ ThO_{2} $ material. The results indicate that larger thoria particles (>1 μm) deform concomitantly with the matrix to cigar-shaped part...

| 520 | |a Abstract The distribution and deformation characteristics of $ ThO_{2} $ particles during processing from powder to wire have been investigated in a W-1 wt pct $ ThO_{2} $ material. The results indicate that larger thoria particles (>1 μm) deform concomitantly with the matrix to cigar-shaped particles and then fracture into segments as deformation of the matrix continues. Smaller particles remain relatively spherical and are not deformed. The net effect of this process is to superpose a nonuniform distribution of large particle segments on a background of small, undeformed, uniformly distributed particles. The consequences of this change in thoria dispersion morphology in reference to work hardening, recrystallization, and fracture of tungsten-thoria materials are discussed. In addition, some conclusions are drawn as to the origin of the large, deformable thoria particles and the effect of different processing modes on the resultant dispersion morphology. | ||

Effect of deformation on $ ThO_{2} $ particle morphology in W-1 Wt Pct $ ThO_{2} $ materials |
| abstract |
Abstract The distribution and deformation characteristics of $ ThO_{2} $ particles during processing from powder to wire have been investigated in a W-1 wt pct $ ThO_{2} $ material. The results indicate that larger thoria particles (>1 μm) deform concomitantly with the matrix to cigar-shaped particles and then fracture into segments as deformation of the matrix continues. Smaller particles remain relatively spherical and are not deformed. The net effect of this process is to superpose a nonuniform distribution of large particle segments on a background of small, undeformed, uniformly distributed particles. The consequences of this change in thoria dispersion morphology in reference to work hardening, recrystallization, and fracture of tungsten-thoria materials are discussed. In addition, some conclusions are drawn as to the origin of the large, deformable thoria particles and the effect of different processing modes on the resultant dispersion morphology. © The Metallurgical Society of American Institute of Mining, Mitallurgical and Petroleum Engineers, Inc., and American Society for Metals 1971 |
