What would be the best material to construct a starship with:
Lets try to figure out whats the strongest. How many times stronger than steel these materials are.


Trinium: 100 times lighter and stronger than steel
Titanium: 5 times stronger than steel
Tritanium: uknown (It is known that it is 21.4 times stronger than diamond, so if any body can figure out how many times stronger diamond is. Well we can calculate from there.)
Duranium: Uknown (but we do know that it stronger than tritanium, It will just have to be a guess)
Durasteel: Uknown (And i could not find any clues, so this will have to be a guess to)

One thing about Trinium-Carter said "100 times lighter and stronger than steel " but could she have meant "100 times lighter, and stronger than Steel"-meaning Trinium was just 100 times lighter but Stronger than Steel??????????????????

[ZPMLOVER]

NO, it one hundred times stronger to. I would like to Add naquadah as well.
Plus to many sights say that it is both, so don't start a big debate thats not what this thread is for. start one with that question. Stay on topic please.

just a not dureasteel is a good conductor so energy from wepons fire is efectively spread acros a larger area

[Crazy Tom]

Durasteel, duranium, and tritanium are not cannon materials featured in SG.

It is however known, that the latest generation Asgard warships used a trinium/carbon/naquadah allow; given their mastery of molecular manipulation, I'd speculate that is was a naqudah molecule, encased within a bucky ball, wich is in turn suspended in a trinium matrix. I'd also guess this material is very hard to produce, which is why the Asgard couln't simple build a massive army over night.

But I don't know much about metalurgy, so anyone who does, please input.

Buckypaper: 500 times stronger than steel, 10 times lighter, and we can build it now

carbon-trinium-naquahdah is the strongest alloy the asgard ever made. so its terribly powerfull

Those are from other Scifis

Trinium
Steel doesen't even have a sg of 10 are you saying trinium is 10+x lighter than water?

Titanium
Significantly lighter than steel but a very weak metal. Ti alloys can match the strength and fatigue resistance of any steel alloy though. The very strong steel alloys are BCC which would be prone to catostrophic failure in the cold of space giving some advantage to Ti alloys. The Ti alloys which are BCC would be worthless in space but the HCP alloys might be OK (really need FCC). The FCC cryo steel alloys would be favored over Ti alloys I would think.

Aluminum
Some Al alloys show a lot of promise. If the right combination of alloying elements and heat treatment were used this would be promising. Al alloys would make good ablative armor and could dissapate the energy from blasts but there would need to be some kind of refractory alloy behind it as it can't take the temperature. The melting points are low enough that Al and copper ablative armors could be easily injected thru ports to build up skin thickness.

Ni-Cr and refractory metals
These are ultra hard ultra high temp alloys but we'd need to mine asteroids because there isn't enough of this stuff on the open market.

steel
There are many cryogenic FCC alloys that would provide adequate service.

No we can't make any sort of bucky material in 1000 ton quantities.

Cermet composites would work as armor panels. This is a blend of ceramic and metal with metal providing some mallability. Remember in order to absorb energy you must have some deformation. Resiliancy is a function of elastic limit stress and elastic strain. They actually make storm trooper armor that withstand 50 caliber armor peircing rounds its just that your body would be hamburger inside.

You could also make panels out of carbon fibers with vapor deposited carbon/metal/whatever.

[Crazy Tom]

Ok; but I don't really know what your talking about... BCC HCB FCC, those mean nothing to me, and I'd wager most of us here, so, could you please explain in greater detial?

PS. It may be possible to use Asgard sensors and beaming technology to isolate where in a planet's core certain metals reside and teleport them straight out, making a cheaper and more productive alternative to asteroid mining.

[thekillman]

it would need MAJOR reprogramming, long range beaming, extreme calculating abilities, and precise and deep penetration sensors, but its possible

No doubt. A specialised platform would sertainly be required.

carbon nanotubes from which buckypaper is made are actually fairly easy to produce
