Annotation The laser optoacoustic method of elastic modules measurement of isotropic aluminum matrix composites is proposed and experimentally realized. The method is based on measurements of phase velocities of thermooptically excited pulses of longitudinal and shear acoustic waves in samples under study. The composite samples were manufactured by reactive cast of aluminum with titanium microparticles and nanoparticles of synthetic diamond mixed into the melt.
Key words aluminum-matrix composite materials, reaction casting, micro-and nanosized particles, microstructure, laser opto-acoustic method, longitudinal and shear acoustic waves, elastic moduli.
