<p>The present invention relates to a method and an apparatus for heat-treating a titanium plate. The method for heat-treating a titanium plate includes a step of reducing pressure in a heat-treatment chamber after placing a titanium plate in the heat-treatment chamber; a step of primarily heating and maintaining the heat-treatment chamber up to a first temperature; a step of secondarily heating and maintaining the heat-treatment chamber up to a second temperature; and a step of introducing and maintaining nitrogen gas into the heat-treatment chamber. The method and the apparatus for heat-treating a titanium plate can introduce nitrogen gas into the heat-treatment chamber after secondarily heating and maintaining, thereby increasing hardness as well as maintaining formability of the titanium plate.</p> |
