The temperature dependent stress-strain curves of Nylon 6 were obtained via tensile hot stage
and the in situ WAXS experiments were measured simultaneously.The results indicated that the temperature related yield stress
breaking strength and modulus of Nylon 6 can be described by the Arrhenius equation.During the process of stretching Nylon 6 experienced elastic deformation
yield
strain hardening and fracture.The yielding on Nylon 6 stress-strain curves was unobvious with the low draw rate
meanwhile
the yielding turned to more unobvious gradually at higher stretching temperatures.The stress-strain curves of Nylon 6 are similar to each other within the measured temperature range.Nevertheless
the yield strength and modulus decreased with the increasing of stretching temperature.By analyzing the WAXS profile
it was found that the -phase: -phase ratio of undeformed Nylon 6 samples decreased along with the temperature increased.Also
at high temperatures
the crystalline phase of Nylon 6 slipped and/or melted during tensile deformation more easily.In the meantime
the relationship between the stretching temperature and mechanical properties was obtained after fitting the temperature dependent results.It was found that the temperature related relationship obeys the Arrhenius equation.In addition
the viscosity dependence of yield stress was given in the paper.
