摘要： A method for producing a high temperature component includes a shaping step of shaping a powder compact of a desired high temperature component shape using a specific powder shaping method, from an alloy powder of γ′ precipitation strengthening-type Ni-based alloy, and a crystal grain coarsening step of coarsening a crystal grain size of the powder compact by heat treatment, wherein the powder compact contains 0.002% or more and 0.07% or less of C, and 5.40% or more and 8.40% or less of Al+Ti by mass percentage.

摘要： A rotor assembly component which is a component of a gas turbine engine is provided with a rotor assembly component body made from a metal, and a hard particle layer including a mass of hard particles and a matrix material, with the hard particles being made from a material harder than a material forming the rotor assembly component body. The matrix material is made solely from the material forming the rotor assembly component body. The hard particle layer is supported directly on a surface of the rotor assembly component body.

摘要： A shaped article production method includes: fabricating an intermediate article by powder bed fusion using a powder of a gamma prime precipitation strengthening Ni-based alloy; and heat-treating the intermediate article. The Ni-based alloy contains, in percent by mass, 7.0 to 17.0% Cr, 7.0 to 12.0% Co, 5.0 to 8.0% Al+Ti, 2.0 to 12.0% W, 1.5 to 4.4% Nb+Ta, 2.3% or less Mo, 0.3% or less C, 2.0% or less Hf, and 0.2% or less Zr. The fabricating the intermediate article includes applying a laser beam to a layer (3) of the powder along scan lines (4) parallel to one another. In applying the laser beam, a value obtained by dividing a pitch between the scan lines (4) by a laser spot diameter is in the range of 0.6 to 1.1.

摘要： A first pre-sintered body composed of a powder made of a first Ni-based alloy is prepared, and a second pre-sintered body composed of a powder made of a second Ni-based alloy is prepared. Subsequently, the first and second pre-sintered bodies are positioned to face each other across a predetermined gap, and a joining material made of a Ni-based alloy having a lower liquidus temperature than the first and second Ni-based alloys is placed in a space that adjoins the first and second pre-sintered bodies and to which the gap opens. After the placing of the joining material, the first and second pre-sintered bodies are heated to melt the joining material, fill the gap with the molten joining material, and subsequently turn the first and second pre-sintered bodies into first and second sintered bodies, respectively.
