Average grain diameter at 310MPa from 2 known yield/grain values

  1. Dec 13, 2008 #1
    1. The problem statement, all variables and given/known data
    The lower yield point for an iron that has an average grain diameter of 1e-2mm is 230MPa. At a grain diameter of 6e-3mm, the yield point increases to 275MPa. At what grain diameter will the lower yield point be 310MPa?


    2. Relevant equations
    Not sure


    3. The attempt at a solution
    Not sure how to do it.
