How can I find material properties of metallic glasses?

I am now going to model a sample with metallic glass (Cu-Zr-Ti) under stress and temperature loads. I wonder whether there is some existing database to find material properties, in particular, the creep properties with respect to temperature and stresses. Then I can use these data as input for a FE analysis.

Thank you very much!

I know this is not what you are looking for, but here is a New York Times article today on the science of glasses, or the lack of it.  Cannot resist to posting the link here.

Hey Gan,

I usually use http://www.matweb.com to get the material properties. I just gave a search for "metallic glass" (I know its very naive :-)), the folowing is what I got:

The properties are for Nickel/Iron/Silicon/Boron Alloy may not be useful to you and also it is basic information.

Thank you for the information!

It is realy difficult to find material properties to put into FE simulations.After I find some, I will update this post.
