摘要： An alloy disc includes a hub portion, a rim portion and a web portion disposed between the hub portion and the rim portion. The disc includes a fine grain structure substantially in a first region of the disc and a coarse grain structure substantially in a second region of the disc. The fine grain structure may be in the hub portion of the disc, and the coarse grain structure may be in the rim portion of the disc. The coarse grain structure may extend a greater distance radially inwardly from the rim portion into the web portion on the first axial end of the disc than on the second axial end of the disc. The fine grain structure may extend a greater distance radially outwardly from the hub portion into the web portion on the second axial end of the disc than on the first axial end of the disc.

摘要： A method of heat treating a superalloy component comprises solution heat treating the component at a temperature below the gamma prime solvus temperature to produce a fine grain structure in the component. Insulation is placed over a first area of the component to form an insulated assembly. The insulated assembly is placed in a furnace at a temperature below the solvus temperature and maintained at that temperature for a predetermined time to achieve a uniform temperature in the component. The temperature is increased at a predetermined rate to a temperature above the solvus temperature to maintain a fine grain structure in a first region, to produce a coarse grain structure in a second region and to produce a transitional structure in a third region between the first and second regions of the component. The insulated assembly is removed from the furnace when the second region of the component has been above the solvus temperature for a predetermined time and/or the first region of the component has reached a predetermined temperature.
摘要翻译：热处理超合金部件的方法包括在低于伽马质子溶质温度的温度下对组分进行固溶热处理，以在组分中产生细晶粒结构。绝缘被放置在部件的第一区域上以形成绝缘组件。将绝缘组件放置在低于固溶温度的温度下的炉中，并在该温度下保持预定时间，以实现组分中均匀的温度。温度以预定速率增加到高于溶剂温度的温度，以在第一区域中保持细晶粒结构，以在第二区域中产生粗晶粒结构，并在第一区域和第二区域之间的第三区域产生过渡结构组件的第二个区域。当组件的第二区域已经高于固相温度达预定时间和/或部件的第一区域已经达到预定温度时，将绝热组件从炉中移除。

摘要： The present invention relates to a method of manufacturing a multiple composition component 10, comprising: arranging first, second and third constituent parts 40, 30, 42 having first, second and third compositions respectively A, B, C so that the first constituent part 40 shares a first boundary with the second constituent part 30 and the second constituent part 30 shares a second boundary with the third constituent part 40. The first, second and third constituent parts 40, 30, 42 are each either a powder or a solid so that the first and second boundaries are each a solid adjacent to a powder. The arrangement is then processed so as to form a single solid component having first, second and third regions 16, 18, 20 having first, second and third compositions A, B, C respectively.
