Positronium formation in semicrystalline poly(ethylene terephthalate)
(Elsevier, 1994-01)
The probability of positronium (Ps) formation in semicrystalline poly(ethylene terephthalate) (PET), has been investigated by means of positron annihilation lifetime spectroscopy (p.a.l.s.). The p.a.l.s. data are correlated ...
Fatigue craze initiation in polycarbonate: study by small-angle X-ray scattering
(Elsevier, 1994-09)
The structural changes that occur during the incubation stage of tensile fatigue failure of glassy polycarbonate are investigated by means of small-angle X-ray scattering. The results are interpreted as the formation of ...
Fatigue craze initiation in polycarbonate: study by transmission electron microscopy
(Elsevier, 1994-08)
Fatigue craze initiation in bulk, amorphous polycarbonate (PC) is investigated by means of transmission electron microscopy. The results agree very well with small angle X-ray scattering measurements of the same set of ...
