4. Conclusions
- Cryogenic milling changed initial ball-shaped powder particles into disk-shaped ones. Powder particles were not refined, but they were intensively deformed, similarly to severe plastic deformation methods (SPD).
- The microstructure of the sintered milled powder consisted of β-grains with the size in range of few micrometers and submicrometer α-phase precipitates.
- The microhardness reached 350 HV and was affected by residual porosity, microstructure, contamination by oxygen and phase composition.
- Both sintered powders possessed the high yield tensile strength of 1200 MPa, but very low ductility.
