摘要： A method is provided of determining the internal cross-sectional area of a pipe along its length. The method includes the steps of:(a) filling the pipe with a first fluid;(b) feeding a second fluid into the pipe at a known flow rate, a meniscus being formed between the first and the second fluid, and the meniscus moving along the pipe as the second fluid displaces the first fluid in the pipe;(c) ultrasonically detecting the position of the meniscus as it moves along the pipe; and(d) determining from the second fluid flow rate and the meniscus position, the internal cross-sectional area of the pipe along its length.

摘要： A method of heat treating a superalloy component includes solution heat treating the component at a temperature below the gamma prime solvus temperature to produce a fine grain structure. Insulation is placed over a first area to form an insulated assembly that 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. 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, produce a coarse grain structure in a second region and produce a transitional structure in a third region between the first and second regions. The insulated assembly is removed from the furnace when the second region has been above the solvus temperature for a predetermined time and/or the first region has reached a predetermined temperature.
