Q

What is confusion factor?

A

~ the substantial re-ordering required to form a multi-cation compound or substantial diffusion required to form multiple phases
~ promotes glass formation

Q

What are bulk metallic glasses?

A

~ confusion factor and atoms with significantly different size give low free volume = higher viscosity

Q

What are applications for bulk metallic glasses?

A

~ golf club heads
~ high frequency transformers (add iron for high electrical resistance, no GB impede ferromagnetic domain motion gives low loss cores)
