COOL CONTEST.
Where do these people come up with all these names?
Niobium - Alloying element in nickel and
cobalt-base superalloys and SS
steel.Yeah right!
Osmium - I like the sound of that one!
Useful for its hardness and re-
sistance to wear.Used for fountain
pen nibs,phonograph needles and
maybe.....knive steel? Don`t think
so.
Yttrium - Deoxidizer for vanadium,highest
tensile strength of the rare earth
metals and used as a micro-cooler
in some Russian titanium alloys to
aid in welding characteristics...
come on fellow knife nuts!!!!
(even if you spell it correctly it
looks wrong)
Now a good knife steel should have a little
Wolfram in it and most steel alloys have teeny amounts of P and Si....but??
Later on in the post someone mentioned
"process by which the secret ingredient is secretly added." Where is 007 when you need him?This leads me back to my first thoughts about interstitial alloying elements (oxy-
gen,nitrogen,carbon,hydrogen).Interstitial
elements can be added after the metal is made,I know that oxygen is added to ti-
tanium golf shafts during a heat-cycle to
increase tensile strength.
It can`t be hydrogen because hydrogen really
likes it`s self and is small enough to move
around ,link-up and start making cracks!!
Not a good thing in metals.
Nitrogen, oxygen, carbon.....?
My guess is oxygen.
Wait!......carbonitriding.That`s a process of adding carbon and nitrogen into a solid alloy by exposure to suitable gases at
certain temperatures!!
What ever the answer,the main thing is we
all exercised our brain,dusted off a book
or two and had a little fun.
Thanks for putting up with me,
