Titanium powder containing solid-soluted nitrogen, titanium material, and method for producing titanium powder containing solid-soluted nitrogen

A method for producing titanium powder containing a solid-soluted nitrogen, the method comprising:

• heating titanium powder comprising titanium particles in a nitrogen-containing atmosphere to dissolve nitrogen atoms and form a solid solution of nitrogen atoms in a matrix of the titanium particles,
• wherein
• a heating temperature for forming the solid solution of the nitrogen atoms in the matrix of the titanium particles is 400° C. or more and 600° C. or less, and
• the heating causes the titanium particles to have a nitrogen content of 0.1 mass % or more and 0.65 mass % or less.
