Internal friction method: suitable also for structural changes of liquids

Internal friction method, widely used in solid physics previously, is proven to be sensitive also to changes in liquid structure. It has been suggested from the tangent loss angle (tan Φ) that changes in liquid structure can occur as function of temperature in some ordinary binary systems such as Pb–Sn, In–Sn and In–Bi. This finding may be helpful to understand liquid structure changing patterns, therefore enriching the phenomenology of liquid state physics.
