05:51 Jul-04-2002 Re: 7075-T6 Aluminum Ed is correct, anisotropy in grains due to manufacturing (rolling, extrusion, etc.) can cause measureable differences in velocity in the different directions w.r.t. the processing. I don't know the numbers for Al 7075 off hand. The temper (the T6) is not really important.
: Don: : Dale Ensminger in his textbook published velocity for this aluminium as: : Long.=6350 m/s and Shear = 3100 m/s : (no surface wave value published). . : However, discussions with Fred Hotchkiss in Panametrics indicated that some aluminiums may have anisotropy to deal with... . : Ed . : : : I'm looking for the speed of sound in 7075-T6 Aluminum. I would like to get Shear wave, Longitudinal wave and Surface wave velocities if possible. : . .
