摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a β titanium alloy bolt at a low cost.
SOLUTION: Plated layers 22, 24 are formed on the outside surface 20 of a cylindrical blank 18 in plating processes P4, P5. After that, a bolt shape blank 50 is formed from the cylindrical blank 18 by cold forging in a cold forging process P7. Therefore, the β titanium alloy does not come into contact with dies 26, 34, 44 during cold forging because the plated layers 22, 24 are located between the dies 26, etc. and the cylindrical blank 18. As a result, the seizure of the cylindrical blank 18 and blanks 32, 42, 50 on the dies 26, etc. is preferably suppressed. Therefore, β titanium alloy bolts 10 can be manufactured at a low cost because the bolt shape blank 50 can be formed by cold forging.

摘要翻译：要解决的问题：提供一种以低成本制造β钛合金螺栓的方法。解决方案：在电镀工艺P4，P5中，在圆柱形坯料18的外表面20上形成镀层22,24。之后，通过冷锻锻造工序P7中的冷锻，由圆筒坯18形成螺栓形坯料50。因此，在冷锻期间，β钛合金不会与模具26,34,44接触，因为镀层22,24位于模具26等和圆柱形坯料18之间。因此，优选地抑制圆柱形坯料18和模具26上的坯料32,42,50等。因此，可以以低成本制造β钛合金螺栓10，因为可以通过冷锻形成螺栓形状坯料50。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a titanium alloy bolt excellent in shape-precision, formed in a net-shape with a cold-forging, and its producing method. SOLUTION: This titanium alloy bolt B is composed of β-type titanium alloy and continues a bolt head 30 with a shaft part 5 for male screw, by cold-forging and is formed as a forged stream line HL along almost the outer-shape. Further, the titanium alloy bolt B having a regular hexagonal shaped (non-circular cross section) hole 32 on the top surface positioned at the opposite side of the shaft part 5 for male screw at the bolt head 30 is also included.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of inexpensively manufacturing a stepped shaft component of titanium alloy.
SOLUTION: Plated layers 22 and 24 are formed on the surface 20 of a shaft material 18 in plating processes P4 and P5. Then, the shaft material 18 is forged into a stepped blank 50 in a cold or warm forging process P7. Since the plated layers 22 and 24 are interposed between a die 26 or 34 or 44 and the shaft material 18, the titanium alloy does not contact the die 26 or the like. This can satisfactorily restrain the shaft material 18 and the blank 32 or 42 or 50 from causing seizure with respect to the die 26 etc., whereby the stepped shaft blank 50 can be formed by forging so that the stepped shaft component 10 of titanium alloy can be manufactured inexpensively.

摘要翻译：要解决的问题：提供能够廉价地制造钛合金的台阶轴部件的方法。解决方案：在电镀工艺P4和P5中，在轴材料18的表面20上形成镀层22和24。然后，在冷或锻造工艺P7中将轴材料18锻造成台阶坯料50。由于镀层22和24夹在模具26或34或44与轴材18之间，所以钛合金不与模具26等接触。这可以令人满意地限制轴材料18和坯料32或42或50相对于模具26等发生卡塞，从而可以通过锻造形成阶梯轴坯料50，使得钛合金的阶梯轴部件10能够廉价制造。版权所有（C）2006，JPO＆NCIPI
