A low-carbon steel has a yield strength of 622 MPa when the average grain diameter is 180 um. When the grain diameter is reduced to 22 um, the yield strength increases to 663 MPa. (a.) Calculate the yield strength when the grain diameter is reduced to 10 μm. Keep track of units, and show all work. (b.) Did we reach the "magical value" of 100 ksi?
