Abstract

Deformation and fracture of partially crystallized Ni55Pd35P10 amorphous alloys have been investigated. The samples with a few percent crystallization show a fracture stress (175 kg mm−2) and apparent Young's modulus (19.5×103kg mm−2) greater than those completely amorphous or partially crystallized 50%. On the other hand, the fracture strain of the former are lower than those of the two latter. A simulated model with mixtures of carborundum powder with grease, shows accord with morphological and mechanical aspects of the partially crystallized alloys. As expected, microcrystals embedded in an amorphous material act as obstacles to plastic flow.
