| Abstract: | The as-quenched microstructures of low carbon steels were observed by scanning electron microscope, and the thin foil specimen was examined by transmission electron microscopy. It is found that the space morphology of low carbon martensite is not lath-like but thin sheet-like, which is designated as sheet-like martensite or packet thin sheet martensite. A three-dimensional model was presented. The reason for exhibiting two apparent morphologies, i.e. double contrast packet and simple contrast packet, in as-quenched low carbon steels was analyzed in detail. It is suggested that the data of martensitic habit plane measured by other procedures should be further inspected using optical metallographic method. The apparent morphologies of low carbon martensite confirm that its habit plane should be {557}_r, rather than {111}_r, {345}_r, nor {213}_r. |
