Would it be possible to mix titanium and steel?

Theoretically, could it be possible to mix titanium and steel and get the best of both? Let’s just assume that cost and difficulty are not an issue? Imagine the possible uses for a metal that was non-magnetic, non-conductive, corrosion resistant, and with a great strength to weight ratio, while being as hard as tempered steel. For one thing, it make a fantistic knife.

So, the question is;
Would it be possible.

That's not how material science works. You don't just mix two or more metals together and get the best out of each base metal. It's a give and take. With high strength comes brittleness, with good ductility comes weakness, etc, etc. Everything you described is basically Ti, adding the steel just lowers your strength-to-weight ratio.

Okay, thanks for a nice clear answer. Now that I think about it, the question was kind of dumb. After I read your answer, I had one of those "Why didn't I think of that" moments.

Welding tips are titanium and conduct heavy electric current to a metal weld.

Welding tips are tungsten IME.

Darn, I'm getting old....
Only just this moment did I recall Titanium is used in aircraft and turbine flywheel rims.

It "Titanium" is a metal that comes from Russia in 50 gal drums in
a form called "sponge"  see pic and is arc melted into great ingots
in a 20 foot tall O₂ free furnace.

Discovered in your Cornwall by William Gregor. It is the highest strength
to weight ratio of any metal, it is used in space craft and jet engines...
Titanium is as strong as some steels but 45% lighter and a poor
conductor of electricity which I read.

Read the Wikipedia article on it

http://en.wikipedia.org/wiki/Titanium

Titanium can be alloyed with iron, aluminium, vanadium, molybdenum, among other elements, to produce strong lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp, and paper), automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications.[2]

The two most useful properties of the metal form are corrosion resistance and the highest strength-to-weight ratio of any metal.[5] In its unalloyed condition, titanium is as strong as some steels, but 45% lighter.[6] There are two allotropic forms[7] and five naturally occurring isotopes of this element, 46Ti through 50Ti, with 48Ti being the most abundant (73.8%).[8] Titanium's properties are chemically and physically similar to zirconium, because both of them have the same number of valence electrons and are in the same group in the periodic table.


SOOO- Titanium is already alloyed with IRON, not steal as Steve brought out, which is already an alloy.

No, because "steel" isn't a metal, its a solid solution of iron and carbon. Does ferro-titanium exist ? yes, but its not got any of the desirable properties of your proposed alloy. Its used to clean steel, because the titanium is extremely reactive

Where do you get the idea that titanium is non-conductive ?
