Abstract : Electron microscope studies of the substructure of nickel strengthened by dispersed particles of thoria were made . The particle size distribution of thoria in the 'as received' material was determined from electron transmission micrographs of thin films, as a basis for future studies of the effect of temperature upon size distribution and bulk strength. In addition, a color photography technique were developed which will be employed in studies of dispersed particles.
