Growth behavior of ferrite allotriomorphs nucleated on grain boundary faces in a low carbon steel
Source abstract
Abstract
The growth behavior of ferrite allotriomorphs nucleated on grain boundary faces in a low carbon steel was revealed by means of serial sectioning and three-dimensional (3-D) computer-aided reconstruction techniques. The length, width and thickness of ferrite allotriomorphs were measured on the basis of 3-D reconstructed images. The measurements indicated that the lengthening of ferrite allotriomorphs was much larger than that of widening and thickening. As isothermal holding time prolonged, adjacent ferrite allotriomorphs impinged against each other and gradually coalesced and finally covered grain boundary faces. The measured growth rate constant was smaller than that calculated, which was probably attributed to solute drag-like effect of manganese in the alloy.
