Re: Aluminium Surface Wave Velocity ----------- Start Original Message ----------- : Hi, : Does anybody have a reference that quotes a range of Surface Wave Velocities for different Aluminium Alloys? : I need an approximate figure to be able to calculate the second Critical Angle to generate surface waves in Aluminium Castings, or alternatively, an Incident Angle in Water to gererate these. : Godfrey Hands ------------ End Original Message ------------
Dear Godfrey, I have a couple of references that I found a few years ago that you can probably use as a guide.
Al 1100-0 (2SO) Velocity of sound (Surface) 2900m/s
Al 2024 T4 (24ST)Velocity of sound (Surface) 2950m/s
These came from the Xactex Corp booklet dated August 1995
