Abstract
A hydrogenation-dehydrogenation method for a TiAl alloy includes performing hydrogenation treatment of the TiAl alloy in an environment of a set temperature equal to or higher than a temperature at which phase transformation to a β phase starts; and performing dehydrogenation treatment of the TiAl alloy which has been subjected to the hydrogenation treatment. The set temperature ranges from 1,100° C. to 1,600° C.
