Abstract:
Research on the following 5 reports is summarized 1 The effect of temperature on local order diffuse scattering from alloys. I 2 The effect of temperature on local order diffuse scattering from alloys. II. Alloys with atomic size effects 3 Short-range order in Cu3Au 4 Order in beta-AgCd and 5 Solid solubility of Pb in Mg below 300 C. Problems considered during the report period included order-disorder transformations, lattice vibrations, point imperfections and diffraction theory. Research was incomplete on a A neutron diffraction study of short range order in beta-brass b Order in FeCo and FeCr alloys c Temperature diffuse scattering in powders and d Point defects in crystals. Measurements were made in the beta-brass study of the diffuse scattering of monochromatic thermal neutrons from single crystals of beta brass at temperatures above the critical temperature. Long range ordering in FeCo, Fe3Co and FeCrb was investigated by neutron diffraction.
