Literature vs test: Al 356 alloying

  1. Apr 14, 2010 #1
    Hi guys, first post here, since I can't find any literature I might as well try a forum. Literature states that Al356 alloy has a Young's Modulus of ~70GPa, of course it will change with tempering and aging differences, but it should be around there. My experiments at school are only yielding around 4-5GPa as maximum Young's Modulus, where the lower values can go as low as 1.5GPa. Does anyone know what is going on, if this is a common occurance or maybe our MTS testing machines just aren't calibrated right?

    Thanks in advance.

    Hi shaneinhisroo, welcome to PF. The Young's modulus isn't going to change much even with temperature and processing. Sounds like your machine (or analysis approach?) is at fault.
