A creep reinforcement material including at least one element selected from B, W, Cr, Mo, Nb, V, Hf, Zr, Ti, Cu, and Co is applied to or thermally sprayed on a surface of a heat-resistant metal member produced using a heat-resistant metal, a section having the creep reinforcement material applied thereto or thermally sprayed thereon is covered by a heat-resistant cover member and secured such that the heat-resistant cover member is in contact with said section, and the heat-resistance metal member covered by the heat-resistant cover member is heated to a temperature of at least 1000°C. As a result, a compressive force acts upon the heat-resistant metal member which thermally expands in a direction towards an outer periphery, the thermal expansion of the heat-resistant metal member in the direction towards the outer periphery is restrained, and efficient diffusion and permeation, into the heat-resistant metal member, of the creep reinforcement material on the surface of the heat-resistant metal member, is rendered possible. |
