What is the hardest titanium alloy i can smelt myself?
Recently ive been looking into titanium alloying, i have access to a large amount of chemically pure titanium scrap, and want to alloy it into the hardest possible alloy i can, so i can build some very tiny yet strong mechanical objects as well as a titanium knife.
the means by which i wish to produce the alloy is with an induction furnace
My problem is, ive google searched, but cant find what the hardest suitable titanium alloy is, previously i thought titanium steel was hardest, but then i learnt that titanium aluminium is the best. Everywhere indirect terms are used like "best" and "most " and often they only talk about pure titanium vs steel alloys. Im really confused. I just want to know what the hardest titanium alloy is.
What is the best titanium alloy i should make for use as a blade and for high strength structuring, e.g frame body for small robot i want to make as indestructable as possible.
