摘要：

Structural relaxation during sub-T(g) annealing was monitored by DSC for three chalcohalide glasses with low glass transition temperatures: Te3I3Se4 (T(g) = 49-degrees-C), Te3Se5Br2 (T(g) = 71-degrees-C) and As4Se3Te2I (T(g) = 118-degrees-C). On annealing at room temperature, the glass with the lowest T(g) relaxed to equilibrium within a few days, the glass with the intermediate T(g) showed substantial relaxation but did not fully equilibrate over a period of months, and the glass with the highest T(g) showed no relaxation in a two month period.
