Abstract

The effect of forming on arsenic selenide glass fiber drawn under extreme conditions are discussed in detail. Differential Scanning Calorimetry (DSC) data are correlated with previously published time-of-flight (TOF) neutron scattering, nuclear quadrupole resonance (NOR) data to argue that the structure of As₂Se₃ glass pulled under extreme conditions is oriented and that some of the extreme structures imposed in the arsenic selenide fibers relax at room temperature. A model is proposed for the sequence of events suggesting a regime of interchain breakage followed by reformation followed by intrachain breakage. Also evident are unexpected small ring structures as a result of low temperature healing process.
