    摘要： A .beta. type titanium alloy material is passed through processes and heating treatments of cold working--intermediate solution treatment--final cold working--final solution treatment--aging. In this process, a structure, which has been provided with strains by the cold working performed prior to the final cold working, will be changed into a recrystallized structure by carrying out the intermediate solution treatment, where uniform and fine micro substructure of dislocations, remain with grains. If such an intermediate solution-treated material is processed with a slight cold working by the final cold working and further with the solution treatment, only a recovery phenomenon progresses, and it is possible to provide such a micro substructure containing more uniform and finer dislocation network not only in grains but also in grain boundaries. Therefore, in the aging, expedition of precipitation and uniform distribution of .alpha. crystals will be realized in the grains and grain boundary regions, and intergranular cracking is difficult to take place, and alloy materials having high strength and high ductility may be produced.

In addition a method is also provided, in which the titanium alloy is produced at lower cost than in a conventional method. The α+β or β titanium alloy contains copper at 1 to 10 mass %, has a crystal phase of β and α phase or of β phase, is formed of crystal particles not more than 100 μm, and has a copper concentration per an arbitrary specified 1 mm3 portion of the crystal phase at within ±40% compared to another arbitrary specified portion. The α+β or β titanium alloy is produced by mixing 1 to 10 mass % of copper powder and the remainder of titanium alloy powder and then pressing and forming while being heated. The method for production of the α+β or β titanium alloy has a step of mixing 1 to 10 mass % of copper powder and the remainder of titanium alloy powder and a step of pressing and forming the mixture while being heated.

    摘要： A process for production of metallic powder comprising contacting a metallic chloride gas with a reductive gas in a temperature range for a reducing reaction to form a metallic powder and subsequently contacting the metallic powder with an inert gas such as nitrogen gas to cool the powder, wherein the rate of cooling is 30° C. or more for temperatures from the temperature range for the reducing reaction to a temperature of 800°C. or less. The metallic powder is rapidly cooled, which results in suppression of agglomeration of particles in the metallic powder and the growth of secondary particles. Growth of particles of a metallic powder formed in a reduction process into secondary particles through agglomeration after the reduction process is suppressed, and a ultrafine metallic powder having a particle diameter of, for example, 1&mgr;m or less, can be reliably produced.
