Ductile fracture surface morphology of amorphous metallic alloys

Fracture surfaces of ductile failure of two types bulk amorphous metallic a lloys were studied using quantitative and qualitative fractographic analysi s. The observed fractographic behaviour of ductile failure in comparison wi th the ductile failure of amorphous alloy ribbons shows signs of the same f ailure mechanisms. Fracture surfaces are created by a meniscus instability process. Some observed morphological differences are explained as the influ ence of different geometric conditions during the voids nucleation, growth, and coalescence.
