    摘要： A method of forging Ni-base superalloys is described which avoids the growth of abnormally large grains in the surface region of a forged article. The method involves forging and/or annealing a Ni-base superalloy in a carburizing environment. Forging and/or annealing in a carburizing environment is done to maintain the carbon concentration in the surface region at a level that is sufficient to prevent the depletion of carbides and carbonitrides. The carburizing environment may also be selected so that it is non-oxidizing with respect to aluminum, in order to prevent the depletion of aluminum and the reduction of the .gamma.' phase in the surface region.

    摘要： A method is provided for obtaining uniform grain growth within .gamma.' precipitation strengthened nickel-base superalloys. The method includes forming a billet having a very fine grain size in order to achieve optimum superplasticity of the superalloy during forging. The article is then heated to a pre-working hold temperature in a manner which prevents coarsening of the microstructure and a loss of superplasticity. The article is then worked, such as by forging, at a temperature below the .gamma.' solvus temperature of the alloy, so as to maintain local strain rates within the article below a critical strain rate for random grain growth, and so as to maintain the strain rate gradient throughout the article below a critical upper limit. After working, the article is subjected to annealing at a temperature which is less than the .gamma.' solvus temperature of the alloy, and for a duration which is sufficient to remove accumulated metallurgical strain in the article. A supersolvus heat treatment is then performed by further heating the article to a temperature above the .GAMMA.' solvus temperature of the superalloy for a duration sufficient to uniformly coarsen the grains of the article.

    摘要： An apparatus for solder joining metal tapes to form laminated metal tapes comprises a channel means having a base, and sidewall means extending therefrom to a cover extending over the sidewall means. The sidewall means define converging channels having an entrance end for admitting the tapes spaced apart, and an exit end where facing tape surfaces can come into contact. The sidewall means separate the base and cover by a distance selected to align the tapes in the width dimension. The cover having a first section extending from the exit end, and a second section extending from the first section to the entrance end, the second section being formed with a cavity facing the channel that permits a solder flow therethrough that minimizes accumulation of particles in the channels. A solder duct means mounted on the channel means for directing molten solder into the channels to flow from the exit end to the entrance end. The solder duct means having a slot extending therethrough and aligned with the exit end. A seal means mounted on the solder duct means adjacent the slot for minimizing solder escaping from the slot while solder coated tapes pass therefrom, and a wiper means mounted on the solder duct means and positioned from the seal means removes exess solder from tapes passing through the seal means.

    摘要： Superconducting tapes having an inner laminate comprised of a parent-metal layer, a superconductive alloy layer on the parent-metal, a reactive-metal layer, and an outer laminate soldered thereon are joined in a superconducting joint by the method of this invention. The outer laminate is removed to form exposed sections, and the tapes are positioned so that the exposed sections are in contact. A melt zone within the exposed sections where the exposed sections are in contact is melted. The melt zone is at least large enough to provide sufficient parent-metal, superconductive alloy, and reactive-metal to form a melt that resolidifies as a continuous precipitate of the superconductive alloy. The melt resolidifies as a continuous precipitate of the superconductive alloy that is continuous with the superconductive alloy on the superconducting tape. Optionally, sections of the outer laminate material corresponding to the size of the exposed sections are bonded to the outermost surfaces of the joined exposed sections.
