Abstract
Metallic glasses are of commercial interest because of their magnetic and mechanical properties. Apart from their embrittlement under given testing conditions which has not yet been fully understood, the ribbons exhibit some inhomogeneities that lead to high failure probabilities for unnotched specimens. Two main types of quenched-in defects can be observed on the rupture surfaces. They are responsible for the specimens failure. For the first time, Weibull theory is successfully applied to the defects distribution in metallic glasses. Three distinct Weibull families of results are distinguished according to Weibull statistics. Two examples of commercial alloys are presented which show the interest of Weibull plots to control the ribbons quality and to follow the evolution of their properties under different conditions of use.
