Siberian Slashers: Russian titanium alloy blades

    This thread presents and documents a series of blades made from a special sheet of Russian titanium alloy. After some experimentation, I've concluded that this complex ti alloy is a unique gem.

    5Al 2Mo 4.5V 1Cr 0.7Fe, a Russian grade called BT23.

    Russians are skilled titanium experts. Ironically, in the 1960's even the titanium needed to build the SR71 Blackbird spy plane, which was made almost entirely of titanium alloy, had to be smuggled into the U.S. through a secret CIA program, to spy on the Soviets from whence it came.

    About 90% of all raw titanium ingots come from Russia. From there, the huge ingots are sent around the world to a handful of titanium smelters that further refine the titanium and alloy it with other elements. The vast majority of ti alloy is all-purpose 6al4v. Much of what's left is one of 4 grades of CP (commercially pure) titanium, unalloyed.

    What's left is turned into various high-alloy titanium stock for special uses, and a tiny fraction of that becomes Mad Science Forge blades!

    A numbered series of ultralight but potent machetes will be made, to give trekkers of the woods something with reach and snappy cutting power, that won't weigh down their packs. The proof of concept:

    A handful of knives will also be made. This ti alloy feels crisp and hard after heat treatment, very icy. A Mecha-style knife:

    Are you going to bring any to the Eugene Oregon show? I would love to see one in person.

    I won't have a table there this year, but I'd sure like to be there, and bring something to show off.

    Seriously, where do you find these exotic Ti alloys anyway? I've called around a few places, and they all think I'm sniffing too many forge fumes...

    Can't wait to see a couple more from this uber Ti.

    Lol! Thanks for the super cool link. I'm sure you'll be able to get ahold of a slasher, dirc. You'd better wait 'till they're finished and take a look before you reserve #5. What if you like #6 better? :D

    My son's favourite number is 5 :) so it won't change, it's been his favourite since age 4... he'll be eventually inheriting this :)

    btw, what thickness is the bt23 stock for this siberian slasher?

    Side question: have you ever tried folding beta Ti to do like a damascus pattern?? lmao, I wouldn't expect it's worth the time, or if the Ti will weld together well

    Thickness is about 1/8" for the Siberian alloy. Titanium doesn't forge-weld, normally. There is "Timascus" and such, which is decorative, and I'm not sure what the limitations are in how it's made. I'm gearing up to make san mai and bi-alloy titanium billets for forged swords - harder edge, springier spine and flats, the different alloy layers visible through polishing. Hopefully the first billets can be made this summer. This is all very hard work and it easily gets overwhelming, but I'm trying! XD

    The slashers will be featured in this thread, and I'll spam you when #5 is coming around.

    In your testing of bt23, did it get harder than your super Ti-Nb alloy you used in the sword? That stuff looked pretty impressive. :) It was 9.5Nb and 0.5Fe if memory serves, and the balance Ti

    I believe it did and does, among other desirable characteristics for a sharp blade. But don't make the mistake of thinking that higher HRc automatically = a better ti knife. There is a lot more to it than a depth measurement of a conical penetrator! The TiNb readings were about 89.5Ti 10Nb 0.5Fe, but the iron could have been rust dust on the surface. The alloy is most likely 90Ti 10Nb.

    Phase 1 of the Siberian Slasher machete project is complete. The first round of light machete blanks is cut and being forged into a more refined shape.

    But what to make of the funny pattern left in the titanium sheet after being cut?

    Like a great beast felled by a hunter of the tundra, the entire carcass if this ti sheet will be used somehow.

    Well in true Mad Science Forge fashion, obviously these drops should be used to make something designed to stab meat. What better use than barbecue skewers!

    These are very flexible but plenty stiff enough to run through any evil interlopers who crash your barbecue.

    The cutting drops yielded 9 skewers. These will be sold, as Daddy needs a new pair of shoes and a big stack of grinding belts.

    A couple more forged pointies that were made slowly while figuring out the alloy:
