Young's Modulus of a single crystal specimen?

  1. Apr 10, 2013 #1
    Does a single crystal specimen have a smaller Young's Modulus than a polycrystalline specimen?

    I think a single crystal would have a lower elastic mudolus since it has less grain boundaries and probably less dislocations than a polycrystalline specimen.

    I'd appreciate any ideas

    Sure it is less than the poly-crystalline. I have some single crystal Aluminum in the laboratory and I can bend the specimen with two fingers only without any real force. I am in the process to find out the young's modulus and all other properties for the single crystal Al
