摘要: Abstract The effects of deformation on the hydrogen absorption/desorption behavior a B2 single-phase Ti–22Al–27Nb (at.%) alloy were investigated mainly by measuring static pressure–composition ( P – C ) isotherms from room temperature to 100°C for specimens quenched 1200°C and deformed 5–∼90% in compression or cold-rolling. β hydride is formed at very low pressure similarly bcc absorbing alloys. In as-quenched specimens, further absorption γ sluggish there no obviously reverse γ→β transformation. Both β→γ transformations are promoted deformation. best properties attained 5–10%, structure which consists well-aligned uniformly distributed screw dislocations. beneficial interpreted terms similarities between atomic displacements around straight dislocations those taking place during β–γ
