The amorphous alloys have been around for some time now, but I hadn't seen this before. Really cool from my structural analyst point of view. http://video.google.com/videoplay?docid=-939151540 119819530 http://www.liquidmetal.com/technology/properties-c omparison/ Can't find a listing of elastic modulus, but it looks to be significantly higher than any other industrial metallic material we're using today. |

It was used in golf clubs more than ten years ago. Interesting stuff. G |

The iPhone 5 is supposed to be made of that stuff. |

isn't this what they used in Star Trek to put the whales in ? |

I believe it can be used like plastic injection molding too. |

CALLING ROB tell EBR you want valves made of Liquidmetal alloy! From the looks of it the valve seats will need a hydraulic buffer to reducer valve bounce! |

How can you have rights to amorphous metals? That is like having rights to plastic or steel... |

"Can't find a listing of elastic modulus..." Blake, Elasticity and Young's modulus are both listed here: http://www.liquidmetal.com/userfiles/file/Prop-Com parison9803.pdf G |

The thing that bugs me a little is looking at the Liquidmetal website - their board is made up of no engineers. They're still trolling for investors. Technology must start SOMEWHERE but I don't see any links any longer to original work done at CalTech a decade ago. http://www.liquidmetal.com/about/board/ I know I'm HIGHLY prejudiced but I'd feel more comfortable with at least ONE materials geek somewhat loosely connected to the company. |

Also - Elastic modulus is a tough call on a hyper-ductile, non-crystalline material when you are looking at stress/strain curve with NO straight line usable for initial modulus. IF they pick an "initial" modulus, of course, it'll be HIGH. |

Psssst, I've got a contact for dilithium crystals, you in? |

Steve, The modulus isn't linear prior to yield? I'm still wondering about the impressive demonstration with the bouncing ball bearing. Thanks for the link Greg. The modulus is surprisingly low, right between aluminum and titanium alloys. |

I'd like to see stress/strain CURVE, not just a number. The actual curve can be very instructive. Modulus of ductile materials can be somewhat subjective. It is "described" as a relatively low strain-to-failure material (not ductile as I had originally mis-read). More detailed discussion: http://www.appropedia.org/Amorphous_Metal_Alloys Kinda cool article on the origins of the stuff: http://spinoff.nasa.gov/Spinoff2004/ch_7.html |

I thought eyephones were "throw away"gadgets.....with all the outdatedness of the silly things. Why make it out of super metal?............. |

Same reason people put carbon fiber buckle guards on their tanks. |

Are those buckle guards really made of carbon fiber? That bouncing bearing made my brain hurt. |

Why are they comparing it to stainless steel? They should be comparing it to spring steel. |

That bouncing ball is just ONE property that is interesting but is just ONE of many. Coefficient of restitution (as illustrated in the bouncing ball) is wildly different than modulus (useful in spring design) The accountants (not engineers) who own the company are carefully chosing the comparisons they are making. |
