报告摘要:The metallic glasses are the topic of many researches because they possess excellent mechanical properties, in particular their yield strength. But these properties depend on many factors: chemical composition, temperature, frequency, applied stress level…. To examine the influence of these numerous factors on the different components of the mechanical response of bulk metallic glasses, many mechanical testing methods are used: dynamic mechanical analysis (DMA), compression or creep tests, thermo-mechanical analysis (TMA ) ... In this oral presentation we briefly review the main results obtained in various bulk metallic glasses. A physical analysis of the mechanical response is presented.
