Differentiating, E˚ with respect to A˚[ least
22.5 for cube texture],we have
dE˚/dA˚ = 0.355 – 0.031[Si wt%] =0 for
minimum MAGNETO-CRYSTALLINE ENERGY
DENSITY.
[Si wt%] = 0.355/0.031 = 11.4516;

2. E˚ = 0.355 * 22.5 + (0.163 – 0.031 * 22.5)
*11.4516– 1.898 = -0.0313802 ≈ ZERO.
MAGNETO-CRYSTALLINE ENERGY DENSITY
SERIES FOR ELECTRICAL STEELS,
E˚ IS POSITIVE FOR [Si wt%] ≤ 11.4516,
ZERO FOR [Si wt%] = 11.4516;
IS NEGATIVE FOR [Si wt%] ≥ 11.4516
