Harmonic_Vibe Posted October 8, 2004 Report Share Posted October 8, 2004 This is something I've been wondering about for awhile. Normally I research stuff online or at the library, but in the spirit of ####'s "CA Aviation Challenge", I've decided to see what the guys and girls on this forum know about this: I know (or at least I've always understood) that the crystalline structure of metal is the 'Achilles Heel' of the material. To eliminate this weakness they grow large crystals (I.E. No "internal" crystalline structure) and thence machine blades from these huge crystals. How do they grow these crystals? I know some of the experiments in space were centered around this. How big can they grow them? Can, or do they make whole turbine wheels out of these things? Am I right about any of this? What about ceramics? Can Adrienne Clarkson really dissolve parliament? And if so, where do I apply for the job? (Just curious) HV Quote Link to comment Share on other sites More sharing options...
