Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solution heat treatment method for manufacturing metallic components of a turbo machine.SOLUTION: In a solution heat treatment method, components 1 provide a hot gas flow channel when assembled in a turbo machine after manufacturing, and the components 1 are subject to a prescribed ime-temperature cycle in a furnace. In the method, the components 1 are disposed in the furnace in the same principle as a component assembly in the turbo machine, but leaving flow areas and gaps 9 between neighboring components 1, then the time-temperature cycle is started, and an inert gas is supplied during the solution heat treatment process, so that the inert gas flows through the flow areas and gaps 9 for achieving a uniform temperature at any time in the solution heat treatment process, in particular, during rapid cool-down and heat-up phases.SELECTED DRAWING: Figure 6 【課題】ターボ機械の金属構成部品を製造するための溶体化熱処理法を提供する。【解決手段】構成部品1は、製造後にターボ機械内で組み立てられたときに高温ガス流通路を提供し、前記構成部品1は、炉内で所定の時間−温度サイクル下に置かれる、溶体化熱処理法に関する。この方法は、前記ターボ機械内の構成部品アッセンブリと同じ原理で、ただし、隣接する構成部品1間に流通面積とギャップ9を残しながら、前記構成部品1を前記炉内に配置し、次いで、前記時間−温度サイクルを開始し、前記溶体化熱処理工程中に不活性ガスを供給し、これにより前記溶体化熱処理工程中のあらゆるタイミングで、特に急速な冷却及び加熱段階において、均一な温度を得るために、前記不活性ガスが前記流通面積とギャップ9を通って流れることを特徴とする。【選択図】図6
