摘要: Bulk metallic glasses have a very high corrosion resistance and mechanical strength. show elastic-perfectly plastic behavior with an extended region of elastic strain (≈ 2%). But at room temperature their macroscopic plasticity is weak even though local observed in shear bands. A relaxation analysis allowed studying micro-mechanisms deformation estimating the apparent activation volume 2000 A3).
