No. Suitable is best. Science serves people but not money. We can't destroy all the old buildings and then rebuild them with 'new' materials, this produce much money but little value. And although R & D is developing in China, it's not an excuse to aimless venture there. And, I am Chinese...

Except mild steel the yield point is difficult to find. So people usually define that the stress at 0.2% inelastic strain is yield strength. You can find the 0.2% inelastic strain position is drawed specially in the graph, that's the reason. And, 0.2% inelastic strain is noticeable in industry...

From one paper I read that localized spin is the cause to this temperature related phenomenon. In my memory only the energy band structure can prove one material is conductor or semiconductor. Not sure if your experiment is strong enough. Seems it's a hot topic in metallic glasses research now...

Zr base metallic glasses are metal-like conductor. You can measure the electric resistance of the sample to prove that.

What about glass fiber?

I think you can refer to regular solution theory. It's also helpful to understand the solid structure.
