Fig. 6 shows fitted true stress−true strain curves by using the Chun et al. model at various strain rates.
Fig. 6 Tension/compression loading curves of the TRIP980 steel sheet fitted by the Chun et al. model at each strain.
The fitted curves with the Chun et al. model show a good prediction with experimental data at all strain rate conditions.
In order to approximate the obtained curves, the Chun et al. model, a modified form of the Chaboche model, is utilized.
Tendencies of the material parameter in the Chun el al model are investigated with respect to the strain rate.

Presences of Al improve the corrosion properties and mostly added to approximately 2-9%.

Generally, in OLEDs based on conjugated polymers (termed as PLEDs), the injection of electrons is more difficult than that of holes due to the large injection barrier present when high work function stable cathode electrodes such as Al or Ag are used.
Finally, thermal evaporation of a 200 nm thick aluminium (Al) cathode completed device fabrication.
Dark and Photo-current density-voltage (J-V) characteristics were measured with a Keithley 2400 source-measure unit while luminance and electroluminescence (EL) spectral characteristics were recorded with an Ocean Optics spectrophotometer equipped with fiber optics, assuming a Lambertian emission profile (for the luminance measurements).
Furthermore, the interaction of Al with reduced WO3 may also be responsible for creating gap states upon electron transfer from Al to WO3 and filling them with electrons.
Note, that the use of a similar thickness reduced WOx layer at the polymer/Al interface results in a shunted device.
