Abstract:

UFACTURING METHODS, Microstructure, Lattices, Impurities. Fundamental properties of high purity w produced both by powder metallurgy techniques and, as single crystals, by electron beam zone melting were studied. High temperature properties of several dispersed second-phase w base alloys were also investigated. Base line data on the metallurgical properties of pure w for temperatures above 2500 F were obtained. The mechanism of purification in w during zone melting was studied. The flow and fracture characteristics of w single crystal were investigated as functions of annealing temperature and atmosphere. Internal friction measurements were carried out at 20 to 800 C on high purity and dosed polycrystalline w wires and w single crystals. Author
