Abstract
This present invention is characterized in that a titanium material on an .alpha. or (.alpha.+.beta.) titanium alloy material hydrogenated in an amount of 0.02 to 2% by weight of hydrogen is heated to a temperature above the .beta. transformation point and below 1100.degree. C., is hot worked in that temperature range at a reduction of 30% or more, the hot working is terminated in a .beta. single phase temperature region, and cooling to 400.degree. C. or less, and annealing in vacuum are then carried out, whereby titanium and titanium alloy materials having a fine acicular microstructure are obtained.
