报告摘要：                                        

Ongoing work in CWRU has focused on the effects of systematic changes in stress state, test temperature, and strain rate on the flow and fracture behavior of metallic glasses.  The presentation will first review the effects of changes in stress state (e.g. superimposed pressure, notches, tension vs. compression, etc.) on the flow/fracture behavior, followed by similar studies conducted at temperatures approaching Tg. This will be followed by an examination of the effects of changes in strain rate/loading rate on the flow and fracture behavior at temperatures up to Tg on tests conducted under both displacement-controlled and load-controlled conditions.  The presentation will include an examination of the effects of changes in sample size on plasticity in such systems on samples prepared via different techniques.
