Abstract
The formation and the growth of shear bands in amorphous metallic alloys have been investigated. The meniscus instability process determines the morphology of fracture surfaces. Cell pattern morphology at fracture surface of amorphous alloys was discussed in the frame of voids distribution patterns. A uniform condition in thin shear band leads to the generation of periodically distributed voids. Triangular pattern of voids in the direction normal to the failure front propagation is obviously observed. These voids act as some initiation centres for plastic deformation. Their spacing correlates with the ductile cell size on the fracture surface. T he gradual events of decohesion in inter-void bridges were developed by means of fractographic analysis.
