摘要

Ultrasonic attenuation capacity of porous Al alloy with high specific strength were studied . The results show that it is a light material that have good ultrasonic attenuation capacity between 1 and 8MHz. Ultrasonic attenuation coefficient a of porous Al alloy increases with decreasing pore diameter d ,with decreasing porosity Ps and with increasing specific surface Sv.
