摘要： A method for producing Ti alloy plates, comprising heating an .alpha.+.beta. Ti alloy ingot to a temperature within the .alpha.+.beta. two phase range, forging or rolling said heated alloy ingot to reduce it more than 30% whereby strain energy accumulates in said ingot as it is being reduced, and reheating said reduced ingot containing said accumulated strain energy to a temperature of the .alpha.+.beta. phase range and then hot rolling said reheated reduced ingot so that it is further reduced in an amount more than an additional 30% whereby said accumulated strain energy accelerates recrystallization during said hot rolling to produce a uniform alloy structure, said heating and reheating being carried out in an atmosphere having not more than 0.02 atm oxygen partial pressure.

摘要： A method of manufacturing a rolled titanium alloy sheet comprises breaking down an .alpha. or .alpha.+.beta. titanium alloy ingot into a slab, working the slab in sequential stages of(A) cross rolling the slab in the .alpha.+.beta. region under a condition of a reduction ratio of at least 1.2 and a cross rolling ratio of 0.6 to 1.4,(B) annealing the workpiece for recrystallization at a temperature 20.degree. to 100.degree. C., preferably 20.degree. to 70.degree. C., below the .beta.-transus of the alloy, and(C) further cross rolling it in the .alpha.+.beta. region under a condition of a reduction ratio of at least 1.6 and a cross rolling ratio of 0.6 to 1.4,and thereafter heat treating the rolled workpiece for annealing, solution treatment and aging or the like, depending on the intended use of the product. The method may include an additional stage (D) of repeating stages (B) and (C) at least once each. The ingot breakdown is preferably carried out by forging or rolling at a temperature of the two-phase .alpha.+.beta. region to a total draft of at least 30%. The heating prior to the hot rolling operations is preferably effected in an atmosphere at a partial pressure of oxygen of 0.02 atm. or below.

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.
