Review on interlamellar spacing and spheroidization rate for hypoeutectoid steel and hypereutectoid steel

open access: yes, 2009
This Final Year Project shows how the rate of spheroidization is dependent on the thickness of the pearlite layers or lamellar. When pearlite microstructure is subjected to an appropriate temperature for a prolong period of time, spheroidization occurs ...
