Abstract

The crystalline, intermediate, and amorphous phase indices were determined by Lindner's X-ray diffraction method and the effect of draw ratio and annealing temperature on the phase indices and the tensile properties were discussed. The intermediate phase increases with draw ratio but slightly decreases with increasing annealing temperature. As the intermediate phase index increases, the initial modulus and breaking stress increase and the breaking strain decreases.
