Abstract
Mechanical properties and microstructure of PTFE at various temperatures were correlated through the effects of temperature and band size on the flow stress and microstructure deformation. Electron microscopic examination of deformed microstructure showed that at low temperatures the crystalline deformation modes (kinking and bowing) were favored, whereas noncrystalline modes (sliding and rotation) were predominant at high temperatures. At low temperatures PTFE showed a crystalline size effect and stress drop phenomenon in its flow‐stress relations not manifested at high temperatures.This publication has 3 references indexed in Scilit:
