Title: The Pitsch-Petch orientation relationship in ferrous pearlite at small undercooling

Abstract

The factors behind the occurrence of the Pitsch-Petch pearlitic orientation relationship (OR) in ferrous systems are investigated using a combination of crystallographic information obtained through electron-backscatter diffraction (EBSD) and knowledge of the three-dimensional (3-D) morphology of pearlite from serial sectioning. Both hypereutectoid and hypoeutectoid ferrous systems of various compositions providing a variety of morphologies are examined to consider the relationship between pearlite nucleation sites and ferrite-cementite interlamellar ORs. It is shown that the Pitsch-Petch OR occurs when a colony is cementite nucleated and this conclusion is valid for both sides of the eutectoid composition.
