Note that the titanium material of the present disclosure is not limited to those produced by the following production methods, and includes those produced by other methods.
  • Patent Document 1 a titanium material is produced by subjecting pure titanium, an ⁇ -titanium alloy, and an ⁇ + ⁇ -titanium alloy to plastic working under a pressure of 1.5 GPa or more with a working strain of 0.5 or more. Since the grain size of the crystal grains constituting the titanium material of Patent Document 1 is as small as several hundred nanometers, it is presumed that the ductility is low. In addition, since the titanium material is produced while applying working strain to the raw material, there is a strain gradient between the central portion and the end portion of the titanium material, which is heterogeneous and reduces mechanical properties such as tensile strength. Inappropriate as a measurement target.

  • a conventional titanium alloy containing 98.8% by mass or more of titanium or pure titanium is prepared as a raw material.
  • the titanium in the titanium alloy and pure titanium is alpha titanium having an alpha phase crystal structure.
  • At least part of the alpha-titanium in the raw material is converted to omega-titanium by the high-pressure and high-temperature treatment under the above conditions.
  • the phase transformation from alpha-titanium to omega-titanium involves rearrangement of atoms. Atomic rearrangement requires energy.
  • the alpha-titanium to omega-titanium phase transformation begins under pressure and temperature above the dashed line indicated by the ⁇ hysteresis in FIG. 3 due to hysteresis effects.
  • Embodiment 4 the high-pressure and high-temperature treatment is performed under pressure and temperature conditions near the dotted line indicated by ⁇ hysteresis in FIG. Under these conditions, the excess pressure is low, and crystal nuclei of omega-titanium are generated only in limited places such as polymerization points of grain boundaries, and excessive generation of crystal nuclei is unlikely to occur. Therefore, it is presumed that the grain size of the crystal grains constituting the obtained titanium material tends to be large and that the obtained titanium material has high ductility.
  • Embodiment 4 graphite with high thermal conductivity (thermal conductivity: 2000 W / (m K)) is used as the heating element of the ultrahigh pressure and high temperature device, and hexagonal boron nitride with high thermal conductivity (thermal conductivity: 600 W/(m ⁇ K)) is used. Since these materials have very high thermal conductivity, temperature gradients are less likely to occur around the raw material during high-pressure, high-temperature processing. Furthermore, since graphite and hexagonal boron nitride are soft, the pressure applied to the sample tends to be even. Therefore, it is presumed that the crystal nuclei grow homogeneously, and the obtained titanium material has a uniform grain size of the crystal grains, and has high strength and high ductility.
