During compression testing of gravity die cast Mg, I am getting modulus value 15-35 GPa. It should be 45 GPa. Why is this variation?

I also tested pressure die casted Mg. It gives modulus ranging from 20 GPa to 40 GPa. Moreover, maximum samples showed modulus values above 25 GPa. I read: pressure die casting helps in removing...
