Changes of mechanical properties and fracture morphology of amorphous tapes involved by heat treatment

The investigation results of influence of heat treatment on the changes of structure, ductility, mechanical properties and particularly fracture morphology of the amorphous CuNi6Sn10P7 and NiP10 tapes have been presented. Morphology of fractures obtained after decohesion process in tensile test shows the history of amorphous alloys crystallization.
