If you google "Titanium blades" you'll see the discussion has come and gone years ago on the SFI forum, and the conclusion is that titanium or its alloys DO NOT make good sword blades for a variety of reasons which people can read for themselves! The complete BS perpetuated by clueless people into hi-tech 'wonder materials' is that titanium is some kind of super tough, super hard indestructible metal, which it definitely isn't. It's stronger than steel for its weight but it's really lightweight like aluminium and if made hard is brittle. The idea of titanium sword blades is a myth that came from the movie 'Blade', not from engineers or materials scientists. It's used to make diving knives which don't corrode in saltwater (and don't need to be particularly sharp or have great edge retention) and short blades for military for explosive ordinance disposal because it's non-magnetic. I'm calling this one pure BS...
It doesn't really seem to be BS, it seems to be a totally functional construction. People make choices for swords all the time, whether they want traditional materials, modern tool steels, or little bits of meteor worked in.
His writing style is certainly ostentatious, but he's not making any absurd claims about it.
It's an interesting concept, even if it hasn't produced good swords yet. Would it be possible to make, say, an extra-long rapier of spring steel around a titanium beam to keep the weight down and the speed up or would that necessarily result in the sword being weak for some reason?

The trick is to make the blade stiff enough. Titanium is 60% of the density of steel, but also only about 60% as stiff. An all-titanium blade would have to be about 20% thicker to maintain the desired stiffness, compared to steel. So it would be about 75% of the weight of a steel blade. For a titanium body with steel edges, you wouldn't save as much weight, and you wouldn't get much extra length or much extra speed.
Might do better with a carbon-fibre reinforced plastic body with steel edges. Or a hollow steel body. Or give up cutting and go for a weight-saving purely thrusting cross-section (like cruciform or extremely hollow ground triangular), in which case a little shorter is better, and you end up with a smallsword.
But, in principle, titanium + steel would work. Not so much gain, at a lot of cost.
"In addition to being efficient, all pole arms were quite nice to look at." - Cherney Berg, A hideous history of weapons, Collier 1963.
The beta ti he is working with has a significant amount of carbon and iron. It might more be regarded as ti infused steel. While being a bit lighter, it is proving to beadifferent animal all together than the thoughts of a pure ti or composite edged attached to a ti body.
libra: Good evening everybody! Haven't been here for a while and never used the shoutbox before. So I'll give it a try...

AndiTheBarvarian: Yes we learn, that's why the Imperium Romanum is known nowadays. Why erase it when it's still lucrative? Those loricae sell like hot cakes!

RufusScorpius: I didn't know barbarians could learn things? Interesting, but you are half Roman on your father's side. Veii was the last Etruscan town conquered by the Romans, then erased from every public record. We only know about it from the Greeks.

AndiTheBarvarian: Veii? Of course we Barbarians know the history of the empires we conquered!

RufusScorpius: All that remains is the memory, and we will soon take care of that as well. Remember the town of Veii? Yah, most people don't either.

AndiTheBarvarian: The only remains are the grins without the enemies!

RufusScorpius: A Noisy Cricket is a gun that your enemies laugh at once.... just once.....

AndiTheBarvarian: Size does matter! We know this from Star Trek, the smaller the phaser is the more powerful it is. Those small types from early NG desintegrated people, the RPG sized later ones just hurt a bit.

RufusScorpius: Love to have a noisy cricket. Don't know why it wasn't liked by Smith's character in the movie except that it didn't look cool. But a pistol that can fit in your front pocket that can blow holes through walls.... hell ya!

Dandelion: Noisy Cricket, anyone? ;-)

Brother Nathaniel: oddj, until then though they have to stick to the sling. It was good enough for king David after all.
