Abstract : The difficulties encountered in upscaling production of atomized superalloy powders from a laboratory scale to commercial quantities are outlined. Ways of overcoming the difficulties are described. Tests on sintered powder billets of Udimet 700 and Inco 713C alloys show that the billets can be readily forged. The mechanical properties of the forged Udimet 700 powder compact compare very favorably with those of the conventional wrought product. The mechanical strengths of Inco 713C alloy, which is usually considered unforgeable, are found to be twice as high as those of the conventional cast material. (Author)
