Abstract
The effects of grain size and shape on alloys of titanium with nitrogen and aluminum have been determined. Increasing α grain size decreases strength and hardness and increases impact resistance. Quenching from the β field produces subgrain markings delineating α plates in Ti-N alloys but not in Ti-Al alloys. This suggests a precipitation from the high nitrogen alloys.
