Exceptions to Zachariasen's rules

Question 1

What are invert glasses?

Answer 1

~ form glasses with moderate cooling
~ just a lot of stuff in it

Question 2

What is confusion factor?

Answer 2

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

Question 3

What are bulk metallic glasses?

Answer 3

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

Question 4

Why do bulk metallic glasses have larger elastic deformations?

Answer 4

~ without periodicity, plastic deformation by dislocation motion is hampered

Question 5

What are applications for bulk metallic glasses?

Answer 5

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