Comprehensive insights into the thermal and mechanical effects of metallic glasses via creep
文献摘要：
Evolution of deformation and relaxation behaviors of a prototypical Cu46Zr46Al8 metallic glass was ex-plored by extensive creep tests under both physical aging and cyclic loading.Deep insights into the microstructure-induced dynamic heterogeneity which accommodates creep deformation were succes-sively revealed via experimental measurements and spectral analyses.An annihilation of local defects within metallic glass with increasing annealing time and cyclic numbers was observed through the re-duction of amplitude in both activation energy spectra and relaxation-time spectra,which were also ac-companied by an ascending value of βKWW.It is further found that the corresponding deformation units within the metallic glass do not disappear permanently,but are recoverable over the course of cyclic loading.The apparent suppressed relaxation process can be gradually alleviated with increasing resum-ing time between two consecutive cycles,behaving differently from physical aging,which indicates a notable discrepancy between thermal treatment and mechanical treatment.
