Noisy metallic glass?

[Endy0816]

Bought a strip off eBay. Trying to figure out if it being noisier than similar strips of metal is just my imagination or not. Any help or thoughts on the subject is appreciated.

I listened to a strip of metal. It wasn't noisy.

 

Would you like to rephrase your question with less emphasis on the assumption that we can read minds?

 Hard to describe exactly but if you hold it in your hand and give it a quick shake, noise results. Was wondering if it might have some use as a noise maker.

Made a quick video.

Well... was it very expensive?

Could you anneal some and find out if that makes a difference?

I assume if you tried to anneal it, that the metal would devitrify.

Is the metal still ductile or is it brittle, since there are no crystal grains?

That's the point.

You would have two bits of metal, one "glass" and the other not, so any difference  would be due to the "glass"

Oh, of course.

The piece I have was twenty dollars, but could probably find it cheaper buying in bulk and use less of it.

Not sure what I can achieve in the way of temperatures, but I'll give that a try for a piece.

I'd say brittle. Really noticeable where it has been cut or is tearing. Half wondering if it can be shattered.

Heat treating one and not the other to compare makes a kind of sense, however the characteristics of many "ordinary" metals vary greatly according to variations of heating and cooling. You may do better tracking down the specific characteristics of that specific metallic glass than attempting to get answers through experimentation.

Kept meaning to update this...

After heating a peice up with standard lighter it shattered upon attempting to get it to flex.
