Metallographic and x-ray spectral studies of alloy powders subjected to mechanical alloying in a planetary centrifugal mill for various periods of time have shown that the high intensity of alloying in this type of mill enables the duration of the process to be reduced to between one-fifth and one-seventh that necessary with the attritors normally used for this purpose. A study was made of the structure and mechanical properties of rods of a dispersion-strengthened Ni-W-Al alloy produced by extrusion of a mechanically alloyed powder. The rods were found to be characterized by a high degree of structural homogeneity, an elongated grain shape resulting from active directional recrystallization during annealing, and a high level of strength at temperatures of up to 1200°C. |
