Cause Analysis of Low Tensile Plasticity in Normal Direction for Hot‐Rolled Thick Plate of HSLA Steel

“…During tensile testing, the MnS was subjected to different forces in different tensile directions. [ 23 ] When the tensile force was along ND, large concentrated stresses occurred on the top and bottom sides of the MnS inclusions, which subsequently led to the formation of microcracks. The microcracks would extend along the top or bottom of the MnS inclusions, eventually leading to brittle fracture around the MnS inclusions.…”

“…A large number of inclusions could disrupt the continuity of the steel matrix and reduce the tensile plasticity of the material. [ 23–28 ] Wu et al investigated the effect of MnS inclusion with long strip morphology on the tensile plasticity of high sulfur steel bar in different directions. [ 23 ] It was shown that the MnS inclusion with long strip morphology caused the tensile plasticity of the bar to different in each direction.…”

“…There are many studies on the effect of MnS inclusions on the tensile plasticity of materials, but they are mainly about high sulfur steels. [ 23–28 ] Little research has been done on low‐sulfur steels with a sulfur content less than 100 ppm. There is a lack of research on the problem of low tensile plasticity in ND of thick plate due to MnS inclusions, and the problem is still prevalent in practical production.…”

“…[ 23–28 ] Wu et al investigated the effect of MnS inclusion with long strip morphology on the tensile plasticity of high sulfur steel bar in different directions. [ 23 ] It was shown that the MnS inclusion with long strip morphology caused the tensile plasticity of the bar to different in each direction. The tensile plasticity perpendicular to the direction of MnS inclusion extension was the worst.…”

Effect of Aging Treatment on Precipitation Strengthening Phase and Mechanical Properties of Al–Cu–Li Alloy

“…The addition of Mg inhibited the coarsening of the PFZs. [2,13,14] In the presence of Mg, the addition of Zn can further improve the strength and corrosion resistance of Al-Cu-Li alloys. Zhang et al [15] investigated effect of Zn on precipitation evolution and mechanical properties of a high strength cast Al-Li-Cu alloy.…”
