October 31, 201311 yr Vette was never Mg, had some Mg in it. Currently it is using the single largest hydroformed piece of alum in the world as part of its frame.Cool that they implemented shape memory alloy in the venting system for the rear hatch as well. If you don't know what shape memory alloys are it is worth a google. Super fucking cool. I've been working with a few Nasa spin offs that are making a solid state airplane (ie no motors to run the wings or engine, but it will fly). Similar in construction to a bi-metal strip like we see in turn signal flashers I assume, only with much slower expansion and contraction rates, yes?
October 31, 201311 yr Admin All that technology on the Vette and they still use vacuum assist braking. LOL.GM yo!
October 31, 201311 yr Lets see here, company screwed up shipping on my replacement cell phone so I had to buy another to get it here for the weekend, smashed my finger open, and bent two 5/8" wrenches, a Gearwrench X beam and a Wright all before 10am. Heck of a day so far.

Speed is controlled by the heating used. Super amazing to see first hand. First piece I held was about 8 years ago. Metal coupon the size of a business card and around 20ga. I bent the shit out of it. Crumpled into a ball. Then hit it with a heat gun and it flattened out PERFECTLY.
October 31, 201311 yr Its cool stuff, I saw it in 06 I think. It was a wire bent into a word, straighten it out, dump in hot water and BAM.
October 31, 201311 yr It is more impressive in sheet form to me. Door dings will someday be a thing of the past. I want memory shape door skins NOW

October 31, 201311 yr Hmph, I found 2 tablespoons of crap in the Miata's air filter. Now I know why it ran better at 75% throttle than at WOT. Going to buy an air and oil filter tomorrow.
October 31, 201311 yr Another option for your Miata, Adrian: http://m1stang.tripod.com/ No way, I need to wash those images away

I bent the shit out of it. Crumpled into a ball. Then hit it with a heat gun and it flattened out PERFECTLY. Interesting. I expected temperature fluctuations to create different final states, not a complete distortion returning to initial form based on temperatures. Seeing the linked spring was cool, but I would really dig the flat form that you saw initially. I assumed high temps would create cooling gaps and low would allow it to return to base form.
November 1, 201311 yr Different materials designed to do different things. Running a "heater" err voltage carrying wire along the material can steer it. ie, solid state plane flaps move either direction depending on heating or not-heating. Obviously balancing near the equilibrium is key for quick changes.
