- Summary form only given, as follows. The influence of interlamellar spacing on the mechanics of deformation was studied and the materials examined ranged from coarse pearlite, with a mean interlamellar spacing λ~0.4 μm, to fine pearlite with λ~0.1 μm. The problems of ex post facto reasoning regarding the modes of deformation were avoided by continuously following deformation with the TV monitor and recording high resolution slow scan micrographs from the same area both before and after straining. The results of this investigation have shown that there are large differences in the deformation and fracture mechanisms between coarse and fine pearlites, especially when the cementite lamellae are aligned close to the tensile axis
