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

, 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 ...

Controlling Interlamellar Spacing in Periodically Grafted Amphiphilic Copolymers

, 2016
We have examined a series of periodically grafted amphiphilic copolymers (PGACs) wherein pendant MPEG segments of varying lengths (TREG, 350, 550, and 750) were grafted at periodic intervals along a long crystallizable alkylene (C-20) backbone.
