Its like hardfacing.

Hey CM...
I just want to say thanks for producing all these informational videos man!
It takes effort, and it taxes the hyper-vigilant sixth sense, which makes me
appreciate you & the videos even more!
I always enjoy the cameos by Dr Bob, Bill W & Big Cat!
Make sure you practice what you preach buddy!
Stay armed, Stay Safe, Stay Alive! Hoo-Ah!
 
Ti and Carbide

72 RC Tungsten Carbide is permanently bonded to the blade in a process that is a bit like welding

The Carbide never wears or flakes off as it is an integral part of the blade both on the exterior and below the surface I've made over 500 knives with this process without a single warranty issue... they just keep on cutting, never rust and are so light you can carry them all the time.
 
EXPLOSION BONDED TITANIUM

Sorry, I just can't get over the MA-2 promo video. Do they come with free steroids and boob jobs?

Hahahahahaha oh my god.

The ma-6 only shipped with a ziplock and takedown instruction, none of the extras you found with the ma-4.

Its' specs and videos will show if you searchbox at www.knifecenter.com

LiquidMetal has several threads on BF. Completely unlike a titanium blade.
 
Cobalt diving knives, very very interesting.

I like blades made of unordinary materials, I'm not really sure what it is about them but i get this feeling that I got to buy them all ( than again it's like that with most knives)

I have the same "affliction" as well as with unusual mechanisms

Daniel , can you clarify what means this 72 RC Tungsten Carbide ? This is not a Rockwell hardness , right ? As far I know tungsten carbide is on Mohs hardness scale and have 8.5 to 9.5 (diamond being 10.0).
 
Dont forget:

The whole thing is solid gold. The fade to black accompanied by a wolf howl after they say "silent" just puts it over the top.

Also a glowing review for the KelTec. Nothing says "I operate bro!" like having your extra mag fall out after two shots.
 
Will Moon recently made some one-off fixed blades out of solid chunks of carbon fiber.

One of the most common non-ferrous metals used is NiTiNOL (current production name SM-100). Combination of Ti, Ni, and various other elements that is much like titanium, but much harder and more flexible (seems like an odd combo but it's true). Ferrum Forge and Duane Dwyer use it often on customs.
 
Charlie Mike- thanks man, that's the best/easiest to get description i've had! (looks kinda fun actually). you always get a pretty toothy edge with that, correct? i mean it can slice, but it's not a slicer-like my kitchen paring knife doesn't make a good knife to baton with. that said :D how fine of an edge can it get?
David Stifle-awesome sword! it's almost sci-fi (guess i'm getting old-ha). is beta ti different from 6al4v or whatever the acronym is, and is your sword then carbidized?
thanks, Neal
p.s.-sorry for all the questions.


Beta ti is a category of titanium alloys, referring to "beta phase metastable," which basically means it's heat-treatable, similar to how high-carbon steel is heat-treated to produce martensite. They can get pretty hard, and are extremely strong, rigid while still staying flexible. Aircraft landing gear leaf springs are a good example of what it's normally used for.

Alpha ti only has "alpha stabilizer" alloying elements within, such as aluminum. Vanadium is an example of a "beta stabilizer," which helps the alloy retain the beta crystal phase at room temperature without decaying back into the alpha phase. "Beta ti" has to have enough beta stabilizing elements within it, relative to its alpha stabilizers, to completely transform the entire piece of metal into the beta phase and retain it after quenching.

6al4v is the basic all-around ti alloy that's good at pretty much everything, and it refers to an alloy of 6% vanadium, 4% aluminum, with the other 90% being the titanium base metal into which the other elements are alloyed. There are a handful of different grades of 6al4v, based on purity. It's categorized as an "alpha-beta" ti alloy, and shares some of the attributes of both alpha-phase ti, and beta-phase ti. It really seems to do well with a carbidized edge.

So there is basically a spectrum in titanium metallurgy, based on the alloy's ability to retain a crystal phase shift, and what can be created through heat-treatment and processing:

Pure ti --- alpha --- near alpha --- alpha-beta ---near beta --- beta
 
Nitinol is/can be memory metal from what I remember reading. That's amazing. How much do those usually go for? I really must own one now that I know this.
I'm not sure if all Nitinol is "memory metal" or what. I am not sure if it has to be so thin or thick, or if it needs special treatment
 
Could you also increase the Martensite amount via cryogenic treatment or is that not necessary or possible with beta-titanium blades?
I only ask because I have no idea :P

Damnit, I meant to put these two posts in to one but hit enter out of habit.

That's a damn good question. I'm not sure what sort of effect a cryogenic treatment could have, but that may be one of them. :]

Cryo isn't necessary for beta titanium blades, but that doesn't mean it's not worth it! :D

This is such an interesting post to me. I know like 6 of the words you said, but my interest is piqued enough that I'm going to look into this more. I definitely appreciate the scale of this kind of knowledge and it only makes me want to learn more. This is he kind of stuff I continue to frequent this forum for.



Oh and all the knife porn. There's that too.
