Abstract

The longitudinal and shear wave velocities in a polycrystalline sample of magnesium thorium alloy were measured by a pulse transmission technique as a function of temperature. Temperatures ranged from 25 C to about 350 deg C for longitudinal wave measurements and to about 220 deg C for shear measurements. The resulting velocity data were used to calculate various elastic properties of the material, including Young’s modulus, shear modulus, bulk modulus, and Poisson’s ratio. The resulting least squares fits for these data are: Longitudinal velocity, cl = 5.749 − 3.987 × 10−4 T − 1.139 × 10−6 T2 mm/μsec; shear velocity, ct = 3.108 − 1.421 × 10−4 T − 2.588 × 10−6 T2 mm/μsec; bulk modulus, B = 3.576 × 10″ − 2.744 × 107 T + 1.187 × 105 T2 dynes/cm2 ; Young’s modulus, E = 4.435 × 10″ − 1.415 × 107 T = 6.037 × 105 T2 dynes/cm2 ; shear modulus, G = 1.716 × 10″ − 7.994 × 106 T − 2.619 × 105 T2 dynes/cm2 ; Poisson’s ratio, σ = 0.293 − 6.459 × 10−6 T + 3.392 × 10−7 T2 .
