Because of its high strength and lightness, it is also excellent in corrosion resistance. It is used in chemical X plants, generators, airplanes, etc. as a structure. Among them, a 2 + /3 type titanium alloy which is high in strength and relatively well-processed is often used.丨王之α Among the products using titanium alloys, there are thin plates, thick plates and bars. Among the bars, there are direct users in their original shape, and the complex shape of the threaded part of the bolts is formed, or the coarseness is added: Γ =, in addition to the excellent elongation of the bar itself, Requires excellent processability. The characteristic property of the bar is 0 1 is a typical manufacturer of the bar, and the ingot produced by the melting is processed into a ° by forging (making a roll material. As shown in Fig. 2, Β, 2Β, 1 1 et) After heating in the hot furnace, the reversible type is used to "add the small embryos to the line. If necessary, the temperature can be applied by the = roll machine. ... The furnace is heated again to the middle of the roll." The degree of alloy bar will be 4, because & can not reach the safety." To the ductility, fatigue, ... the status quo of the rolling text can not be unleashed and the excellent titanium alloy bar. For example,

INSTRUCTION OF THE INVENTION (2) When the temperature of the right-handed material rises above the 10,000-degree point, it becomes a 10,000-phase structure in which the main body is needle-shaped, so that excellent ductility and fatigue characteristics are not obtained. In addition, since the 5/5 metamorphic point is very high, even if the heat is hard to be rolled, the temperature of the material becomes a Ti-6A1-4V alloy having a temperature above the variability point. If the temperature of the roll rises due to processing heat, the grain is promoted. Growing up, the helmet is given excellent ductility, fatigue characteristics and processability. As a method for solving the problem of temperature rise due to processing heat, Japanese Laid-Open Patent Publication No. SHO 59-82-01 discloses that at each of the alpha domain temperature and the =+ dot domain temperature, 1 Roller ring groove 1 - Pass) The reduction in cross section is set to _ below the milk roll method. In addition, it is disclosed in Japanese Unexamined Patent Publication No. Hei. No. 4 discloses a method for suppressing the water-cooling of the light-weighted material by the core 1 in order to suppress the heat generated by the processing. Then, in the paper ίπΐ rt R〇Uing 〇f Tl^6A^4V - a cont.nuous 述· 2 2 92 SCienCe and Techno10^)", remember: ί I processing heat itself must slow down the roll speed To the performance limit of the roll machine used. In the method of the publication of the Gazette No. 59_821Q1 and the publication of JP-A-58_2_, a titanium alloy bar having ductile fatigue cannot be obtained. It is excellent in the properties and the addition of the jade. In the method of the publication No. 59-821 °2, the reduction rate of the cross-section per one ring ring groove is also sufficient depending on the type of the alloy. Furthermore, in the method of the Japanese Patent Publication No. 58-25465, the material is deteriorated due to the absorption of hydrogen, and the production is caused by rapid cooling.
