Description

<p>To quantitatively evaluate the three-dimensional lamellar curvature in pearlitic steel, the crystallographic orientation rotation of ferrite and cementite was analyzed using scanning electron microscopy and electron backscattering diffraction. In the hypereutectoid steel containing 0.92% C, 0.30% Mn, 0.20% Si, and 0.19% Cr, the ferrite–cementite interfaces in some colonies were confirmed to match well with those having frequently observed habit planes with the Pitsch–Petch orientation relationship. It was also confirmed that the ferrite and cementite near the ferrite–cementite interface rotated toward the same orientation to maintain the Pitsch–Petch orientation relationship and the habit plane. Based on the confirmation that the ferrite–cementite interface is well approximated by (010) plane of the adjacent cementite, the lamellae were revealed to have three-dimensional anisotropic curvature.</p>
