Abstract

Neutron diffraction was utilized in the investigation of elastic lattice strain evolution during high-temperature deformation of monolithic in-situ reinforced Si 3N 4 and its SiC-particle composite. Tension experiments were performed near 1400°C using the new SMARTS diffractometer at the Los Alamos Neutron Science Center. The diffraction data provided information about thermal expansion coefficients and elastic constants at high temperature. Also, the hkl-dependent strains were measured.
