Elongated MnS inclusions in HSLA steel produces no detectable burst emission activity when a steel test sample is stressed in tension or in compression along the longitudinal direction. This is in sharp contrast to significant burst emission activities when the tensile stress acts normal to the flattened MnS inclusions in the thickness direction samples of the same HSLA steel. The experimental results are consistent with calculations of internal stresses in and around an oblate inclusion. Author
