Assume that strengthening of a low-carbon steel is achieved by grain size refinement AND by fine carbide dispersions. Uniaxial tensile tests show that the tensile yield stress ?y=379.5 MPa when the grain diameter d is 0.32 mm, and ?y=276 MPa when d=1.0 mm. The shear modulus G=118 GPa and b=2 Å. What is the average distance between the particles?
