Abstract
The ductility of steel plates, especially in the thickness (short-transverse) direction, is sensitive to the number, size, shape and distribution of nonmetallic (MnS, in particular) inclusions. Our previous extensive works on a series of low alloy steels have revealed the anisotropic AE behavior which strongly depends on the sulfur content, the rolling ratio of the plate and the heat treatments. These studies indicated that the decohesion of MnS incluson/matrix interface is the source of most burst type AE during the tensile loading or fracture of ductile steel members. The present study was carried out in order to understand the effect of very low sulfur content on PYBE, particularly in conjunction with the amount and shape of inclusions and the presence of particular alloying element(s) in the steel.
