Abstract (en)
[origin: US2016024631A1] A method of converting an alloy comprising a majority of titanium, the method comprising: a step of fabricating an ingot (1); steps of a first type (A, B, C) of plastically deforming the alloy at a temperature higher than the β transus temperature Tβ; steps of a second type (A′, B′) of plastically deforming the alloy at a temperature lower than the β transus temperature Tβ. These step of the first and second types (A, A′, B, B′, C) are performed in the following sequence: a first step of the first type (A) at a first temperature T1; a first step of the second type (A′); a second step of the first type (B) at a second temperature T2 lower than T1; a second step of the second type (B′); and a third step of the first type (C) at a third temperature T3 lower than T2.
