RE: Grain and structure manipulation via ultrasound
Besides non destructive testing and evaluation, including microstructural differences determination, the following applications are mentioned:
Ultrasonic cleaning,
Ultrasonic welding, brazing, soldering,
Ultrasonic impact grinding,
Ultrasonic machining

I've heard of some studies, but I suspect are proprietary.
If you can accomplish those processes, I don't see why you could not adapt it to grain manipulation.

They have a mechanical device that is supposed to remove thermally induce stresses in metals using a varying frequency device.
I’ve been in contact with them in the past but have not had an opportunity to actually use the device but theory behind it may be similar to what you are looking for.
Gregory Merritt is who I have spoken to in the past. His number is 810-353-2041 or 1-800-META-LAX.
Hope this helps, David

I've been looking at using mag fields to manipulate start temps for a few transformations in alloy steel. I don’t have access to a particle accelerator, or anything approaching a 7 to 30 tesla magnet that the successful tests in the papers use. I could get a .5 to a 1.0 T, as I think it's possible to trade magnet strength for time. I was wondering if I could enhance the mag field with ultrasound to physically align/refine the grain. Even ultrasound by itself ?

Just a thought.

I did a wee search on Materials Transactions, and didnt find much. Thanks
