Effect of Porous Structural Parameters on Ultrasonic Attenuation Capacity of Porous Al Alloy with High Specific Strength

Abstract:

Article Preview

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 α of porous Al alloy increases with decreasing pore diameter d ,with decreasing porosity Ps and with increasing specific surface Sv.
