Some papers claim the higher cooling rate, the bigger undercooling; however I found that higher cooling rate made smaller undercooling, meaning alloy starts freezing earlier than the case of low cooling rate, meanwhile the cooling peak was broader.
The figure shows DSC cooling (blue) and 2nd heating (green) curves (step: 10 K/min) for a commercial sample supplied as Atactic Polypropylene (APP). The heating curve illustrates two major...
