Vv. Polyakov et al., CORRELATIONS BETWEEN ACOUSTICAL AND PHYSICOMECHANICAL CHARACTERISTICSIN THE ULTRASONIC INSPECTION OF POROUS METALS, Russian journal of nondestructive testing, 30(9), 1994, pp. 676-678
Correlations are established between the velocities of longitudinal an
d transverse ultrasonic waves, on the one hand, and the electrical con
ductivity, thermal conductivity, magnetic permeability, and Brinell ha
rdness, on the other, for porous copper and iron. The reliability of t
he correlations for ultrasonic inspection problem is analyzed.
