AN ELECTRON TRANSMISSION STUDY OF OXIDE PARTICLE STATISTICS IN TD-NICKEL ALLOY.
Abstract
Electron microscope studies of the substructure of nickel strengthened by dispersed thorium oxide particles were made. Special attention was paid to the problem of the stability of a strenthening dispersion in terns of particle size distribution and agglomeration with respect to environmental temperatures ranging to the melting point (1450C) of the nickel matrix. Electron microscope dark field techniques was also employed to investigate the crystal structure of individual particles in the above temperature range. Finally, the bulk strength (in terms of microhardness) as a function of time at various temperatures was interpreted in the light of the substructural observations. (Author)
