f] caused by the heat of crystallization, the release of pressure and crystallization kinetics is seen in the knee of the curve.
The curve corresponding to the 75% layer assumes a temperature plateau (130 [degrees] C) at 15 s because heat of crystallization generated by crystallizing resin at positions closer to the skin impedes the transport of heat from that sector.
The effect of different crystallization kinetics for different materials was approached by arbitrarily varying the degree of crystallinity by changing the latent heat of crystallization in the calculation.

Equation of energy, taking into account dependence of thermophysical properties upon temperature and release of latent heat of crystallization within the range of temperatures, is described by Fourier equation of heat conductivity.
By providing more nucleation sites, and, therefore, greater heat of crystallization during solidification, undercooling is minimized and equilibrium solidification is aided.
The melting parameters were calculated from the reheating scans and heat of crystallization from the cooling scans.
