Effect of porous structural parameters on ultrasonic attenuation capacity of porous Al alloy with high specific strength

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.
