摘要	Catastrophic brittle failure prevents the application of bulk metallic glasses (BMGs).The brittle La69Co17Al14 BMG shows large compressive plasticity when compressed in constrained conditions. Here the compressive plasticity of this BMG was systematically studied by decreasing aspect ratio (height/diameter) of the samples in uniaxial compression and the brittleductile transition occurs at an aspect ratio of 0.36. With the increase of the plasticity (decrease of the aspect ratio), the hardness decreases firstly and then increases, however, the relaxation enthalpy indicating its structure increases monotonically. Our findings provide a powerful experimental support for the application of brittle La-based BMGs.
