Crystalized Titanium?

I know little about it, but Boker does that with several of their titanium models. I think it is a chemical process which reveals the structore of the metal. I think it is neat too!
 
Just about all solid Ti is crystalized. Amorphous Ti has only been produced in thin films and it has to be kept in an oxygen-free environment.
 
Any metal are kind of crystal by defenition of metal, as I remember phisic classes (or was it chemestry?).
But what may mean crystalized? I doubt it is monocrystal. May be some kind of coating or chemical treatment?
Thanks, Vassili.

Just about all metals are crystals. In general terms, the purpose of hardening metal is to encourage the formation of a tigher crystal structure.

Take a cup or two of common kitchen flour and sift it. Now pour that into a tall drinking glass. Pick the glass up an few inches and "tap" the bottom of it on the table. With each rap, the level of the flour in the glass will go down. Is flour somehow disappearing? No. The sharp mechanical shock encourages the grains of flour to pack closer together. Similarly, when metal is thermally shocked by heating and cooling, the molecules pack together tigher.

Occationally, I pass a "new age" store. It always ammuses me to see people who think there's some "energy" in crystals. Crystals form because they are the LOWEST energy state of the material in question. I also get a kick out of people who ascribe some special "energy" or power to a "crystal" made of glass but would poo-poo the idea of special "crystal energy" in a lump of steel. Even the glass we call "crystal" is not, in fact, a crystal; it's not even a solid. Glass is an a amorphous superfluid, a very, very thick liquid, not a crystal at all. But a lump of steel is very crystal.

Isn't science wonderful?

Probably has some silver in it then.
 
Woohoo! A chance to be a pedant:

Glass is not a superfluid. Super-fluids are an instance of a Bose-Einstein condensate in which all of the atoms enter the same quantum state. An example would be very cold Helium-4. They flow without viscosity.

Glass is not a liquid. It is a solid. Glass does not slump after hundreds of years (although glass makers several hundred years ago weren't particularly careful about making their glass not slump when they were making windows).
================

More utility and less pedantary: The metal is apparently a titanium aluminum alloy, but I haven't found the specifics yet.

I did find out that a library in the City of Cerritos used "crystallized" titanium panels from CMF (Custom Metal Fabricators), and this neat page of Ti anodizing:

Titanium Anodizing Options at Titanium Finishing Corp.
 
Metallurgy lesson ...Metals do not have molecules ,they have crystals..Heat treating of metals does not pack the crystals tighter...Crystallized in this knife just means large crystals and of course it's anodized. ..The comment on 'kills germs' is somebodies imagination.... Beware of advertising hype !!!
 
I saw it at the Blade show, it is a surface treatment, probably by vapour deposition then etched. The etched surface then can be either left plain or anodized. Quite attractive.
 
TiO2 apparently has some antibacterial properties but only under sunlight (ie. UV) that it is a semiconductor sensitive to UV frequencies. Cannot remember where I read this but I do remember that the source seemed reliable.

you're right, glass isn't a superfluid, it's a super cooled liquid
you're also thinking about helium 2?
 
Boker has been doing this for years on various knives, I think it started with the Omega Linerlock, they also have a kitchen series.

Not sure of the antibacterial properties but I read an explanation some time ago that sounded reasonable - it certainly did not back up the claim that it kills on contact though. One thing for sure is that they are nice to work with in the kitchen because the ti blade will not impart any taste on what you're cutting, nor will it darken the foods it cuts.

Buck also has/had the XLT Ti with a crystallized titanium handle; maybe a post in their forum could get a detailed reply from one of the Buck guys on how they do it.

Actually, Darrel told me it goes all the way thru the material. Its being done by the same guys who coat Rob Simonichs knives, Body Coate???
 
Steel can be antibacterial if it contains silver

AK Steel makes materials specifically this way

http://www.aksteel.com/markets_products/agion.asp

They even built a multi-million dollar concept house extensively using this material.

You gotta check this house out.

http://www.akconcepthome.com/

The AK Steel Concept Home

Nestled into the Simi Valley hillside is the 11,000 square foot AK Steel Concept Home. Utilizing more than 175,000 pounds of steel, this home is the first house ever built with AK Coatings' antimicrobial-coated steel, used to suppress the growth of microbes. Because of its extensive use of steel, the home has built-in protection from many of California's hazards such as earthquakes, fires and termites.

By using structural and cold-formed steel, architects at AC Martin were able to achieve a unique look. Each room in the home contains open spaces without the interruption of support beams and resemble boxes of glass with cathedral-like dimensions. In addition, the modular rooms can easily be partitioned off to conserve energy.

The distinctive home includes:

+ 6,000-bottle wine cellar made with 11,600 pounds of steel
+ Kitchen with six sinks, two cooking ranges and three dishwashers
+ Three-car garage, a library and a gym
+ Three-story entryway with floating steel staircase and elevator
+ 1,600 square foot guest house, linked to the main house by walkways and a piazza

11,000 square feet and three bed rooms if you count the Maid's quarters. It's the ultimate bachelor pad.
 
Gollnick, I think you are correct in crystals not "containing" or storing very much energy. I think the new agers are misstating their case. I think they might actually be refering to crystal's ability to conduct energy. The use of rubies in lasers, and recently an experiment using emerald to produce a higher concentration of photon flux than in the sun are 2 examples of some crystals' ability to conduct, channel and possibly focus some different kinds of energy. Other than that, I agree that they seem to be full of bunk.

I guess since faceted glass also qualifies as a cryatal to them, they are focusing on external perameters and appearances instead of substance. Of course, glass can also channel and focus energy when properly formed...

So, since knives are made of metal crystals, (got to get in the knife content...) they do not contain much power but they are very good at channeling and focusing power? (cool) (Except for that liquid metal stuff, since it is not a crystal. It contains stored energy and "superheats" when splintered. No wonder they want to make projectiles out of it. I wonder how many additional btus or joules of energy are released for each gram that flashes to vapor under high velocity impact? Almost like an explosive round without technically containing any explosives!)

Gabe, are you saying that modern glass will not flow, but some more "primitive" formulations from hundreds of years ago were improperly made or mixed or heated or whatever, and that some of them can flow? I remember vividly the bulges in the bottoms of my grandmother's kitchen windows looking just like a realy slow liquid flowing onto the frame both inside and out. Are you saying that these bulges were in the original installation, or that the substance in her windowframe does not qualify as modern "glass" on technical grounds? This has fascinated me for decades and I would love to know.
 
Yes it was Body Cote that had the sample but the word coating was used, I am just speculating on the technique.

The sparkle effect is not unlike the faceted effect shown by freshly hot dipped galvanized steel where the zinc cools slowly to form large crystal structures on the surface. The exception is that this is titanium.
 
Old windows bulge because of the way the glass was made. The float glass process is still a relatively recent invention compared to the invention of glass.

The glass used to be 'blown' on the end of a tube (like a big bubble) then spun to flatten it out. Where the blowpipe connects to the glass it would be thicker and consequently when cut would not be perfectly flat like modern glass.

I can only assume the thicker part was put in at the bottom of the frame so the pane was not 'top-heavy'. It would only be held in with putty so I think you would probably want to insert it thick side down.

Helium II is the 'colder' form of Helium-4, which gives it it's superfluid characteristics-loads of stuff here >>>

gleaned from a website:

Summary Chemically modifying titanium surface with hydrogen peroxide solutions is an effective method to provide titanium with bioactivity. We eliminated here successfully the harmful subsequent thermal treatment through low-temperature deposition of crystalline titania films (anatase and rutile) which shown excellent in vitro bioactivity. Addition of Ta(V) ions into the hydrogen peroxide solution favors not only the low-temperature crystallization process, but also the formation of rutile phase
