摘要： PROBLEM TO BE SOLVED: To provide a titanium alloy rod wire for a coil spring which can simultaneously and more stably enhance three characteristics of a diameter deviation of the rod wire to be used as a base material, formability for the coil spring, and the uniformity of a distribution of cross-sectional hardness after having been subjected to aging heat treatment, and to provide a production method therefor.
SOLUTION: The diameter deviation of the rod wire can be improved and the deformation resistance of the rod wire can be reduced by applying a drawing rate controlled to as low as 3 to 20% to the titanium alloy rod wire of a base material for the coil spring, when cold-drawing the titanium alloy rod wire. At the same time, by setting the β transformation temperature of the β titanium alloy to 780°C or higher, the precipitation of an α phase is accelerated during aging heat treatment, and the variation of hardness distribution in a cross section can be reduced even when the rod wire is drawn at the low drawing rate and heat-treated for a short period of time. Furthermore, by controlling a metallographic structure of the rod wire before being cold-drawn to a fine unrecrystallized structure or a recrystallized structure having a grain size of 10 μm or less, the variation of the hardness distribution in the cross section after having been heat-treated can be extremely decreased.

摘要： PROBLEM TO BE SOLVED: To provide a titanium material hot rolling method by which flaws caused by the hot rolling, in particular, sticking flaw can be reduced.
SOLUTION: The titanium material hot rolling method is characterized in that when heated titanium material is hot-rolled, the first pass rolling is performed at a temperature of ≥ 750°C and a draft of > 8% without performing descaling before the rolling is started after the heating, then the heated titanium material is hot-rolled in a predetermined shape. Heated scale is uniformly depressed into the surface after the one pass rolling, and pressed into a base titanium. The adhesibility of heated scale is therefore increased, and the finely divided heated scales continuously remain in the surface even when the subsequent rolling is advanced, the sticking of a work to a rolling roll is suppressed and the flaw during the hot rolling can be reduced.

摘要翻译：要解决的问题：提供一种钛热材料热轧方法，由此可以减少由热轧引起的缺陷，特别是粘着缺陷。解决方案：钛材料热轧方法的特征在于，当加热的钛材料被热轧时，在≥700℃的温度和> 8％的温度下进行第一次轧制，而不进行除锈在加热之后开始轧制，然后将加热的钛材料热轧成预定形状。一次轧制后，加热等级均匀地压入表面，并压制成基底钛。因此，加热标尺的粘附性增加，即使当随后的轧制进行时，细分散的加热鳞片也连续地残留在表面中，因此可以抑制工件对轧辊的粘附，并且可以减少热轧期间的缺陷。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a titanium material superior in formability and lubricity, and to provide a manufacturing method therefor.
SOLUTION: The titanium material has the surface layer in which the total concentration of nitrogen, oxygen and carbon, is in the range of 1-8 mass% at 0.5 μm deep parts and 0.2 mass% at 5 μm deep parts from the surface. The effective manufacturing method is characterized by annealing a cold-rolled titanium material in a gaseous nitrogen atmosphere of which the oxygen concentration and the dew point are prescribed, at a predetermined temperature. Furthermore, the more effective method is to continuously annealing a coiled material. Thereby, the titanium material acquires a low coefficient of friction, superior lubricity, a high Erichsen value and superior formability. The above manufacturing method simultaneously achieves formation of the surface having the total concentration of nitrogen, oxygen and carbon in the above range, and annealing after cold rolling.
