Thank you Chipboarder and SC8 for posting the first things that were actually worth reading on this forum in a very long time

Yep, mixed metals often have much lower freeze point than a pure metal, sometimes even non-metallic elements in alloy suppress freeze point, like cast iron having much lower freeze point via high carbon content vs. steel with only a flea fart of carbon that remains alloyed with the Fe upon cooling. Cast iron has so much carbon, it usually cools into two phases, separate carbon graphite flakes (or graphite nodules in case of ductile iron) within steel alloy matrix, hence why most cast iron is typically brittle vs. steel or ductile iron.

Agree that most of this bmg part making is process critical. With bmg formulas, quick cooling rate to freeze alloy into single glass phase is critical. If part is cooled too slowly, it may not be a single glass phase but have separate crystalline regions of different compositions.

So again, just have to wait and see if any new substantial revenues come to LQMT. I'm agnostic on LQMT getting a cut on any orders placed in China. Time will tell.

Chip,

Introduce the zirconium, titanium and vanadium to the initial melt as very fine powders (as close to atomic level as possible would be best!), and let the other metals with lower melt points melt around these particles?

The end result would have to be an amorphous solid when cool, to work and to be BMG

IMHO - Tomcat
