Dynamic studies of the tensile deformation and fracture of pearlite

• High resolution 200 kV scanning electron microscopy has been used to study in situ the tensile deformation and fracture of a range of pearlites, from relatively coarse mean interlamellar spacing of about 400 nm, to very fine mean spacing of about 90 nm. It was found that there were considerable differences in the tensile deformation behaviour between fine and coarse pearlites. A model is proposed to account for the differences based upon a combination of pile-up and fibre loading stresses, in which the operating deformation mode is largely determined by which type of mechanism is dominant
