ABSTRACT

HCP structure. α

Ti alloy

Titanium alloy in which

α

-phase

is the only

phase constituent

after

air-cooling

from the

β

-field in the

phase diagram

concerned. Alloys with a small fraction of

β

-phase

(

5 vol%) are usually related to the same group and are called near-

α

alloys. All the

α

alloys contain

α

-stabilizers.
