This material developed a microstructure with a bimodal grain size distribution, indicating that a complexion transition occurs within this temperature range. The time and temperature dependence of this complexion transition was analyzed and used to produce a grain-boundary complexion TTT diagram for this...

A review of research in the author's laboratory is presented. Interrelationships between reaction conditions and material properties of thermosetting and high Tg polymers are discussed from the point of view of generalized time-temperature-transformation (TTT) diagram. The TBA torsion pendulum is ...
The results are compared with published torsional braid analysis (TBA) studies of the same system using a time-temperature-transformation diagram. The dielectric measurements were made at temperatures between 100 and 220 C using measurement frequencies between 0.1 Hz and 10,000 Hz. The DSC was ...
