Abstract: A process for producing a fine grain forged superalloy article having a high yield strength at intermediate temperatures. A preferred starting composition comprises, by weight, 15 % Cr, 13.6 % Co, 4.1 % Mo, 4.6 % Ti, 2.2 % Al, 0.01 % C, 0.007 % B, 0.07 % Zr, balance Ni. This material is forged at a temperature above the gamma prime solvus and at a true strain of at least 0.5. Alternately, the material may be forged below the gamma prime solvus temperature with intermediate super solvus anneals. The overaged material is then worked at a temperature below the gamma prime solvus. The resultant fine grain material is then heat treated or can be further isothermally forged prior to heat treatment to produce complex shapes.
Abstract translation: 一种在中间温度下具有高屈服强度的细晶粒锻造超合金制品的制造方法。 优选的起始组合物包含15%Cr,13.6%Co,4.1%Mo,4.6%Ti,2.2%Al,0.01%C,0.007%B,0.07%Zr,余量为Ni。 该材料在高于伽玛质子溶液的温度下锻炼,真实应变至少为0.5。 或者,可以用中等超固溶退火将材料锻造成低于伽马质子溶质温度。 然后将过时的材料在低于伽玛质子溶液的温度下进行加工。 然后将所得细晶粒材料进行热处理,或者可以在热处理之前进一步等温锻造以产生复杂形状。

Abstract: On décrit un procédé pour produire un article en superalliage forgé à grain fin présentant une résistance à la déformation élevée à des températures intermédiaires. Une composition de départ préférée comprend, en poids, 15 % Cr, 13,6 % Co, 4,1 % Mo, 4,6 % Ti, 2,2 % Al, 0,01 % C, 0,007 % B, 0,07 % Zr, solde Ni. On forge cette matière à une température supérieure à la courbe limite de solubilité gamma de base et à un taux de déformation réelle d'au moins 0,5. Dans un autre mode de réalisation, on forge la matière à une température inférieure à la température de la courbe limite de solubilité gamma de base avec des recuits intermédiaires de super courbe limite de solubilité. On effectue ensuite le formage de la matière survieillie à une température inférieure à la courbe limite de solubilité gamma de base. On traite alors à chaud la matière à grain fin obtenue ou l'on peut aussi la forger de manière isothermique avant de la traiter à chaud pour produire des formes complexes.
