Experimental Calculation of Viscosity Parameter of Thin Film Microrupture for Multi-Component Amorphous-Nanocrystalline Metallic Alloys by the Local Stress Method
New amorphous and amorphous-nanocrystalline materials have a unique set of physical properties. In some cases, these materials are used in practice. Creation and usage of new materials demand control for their condition and development of mechanical testing methods. Traditional methods of mechanical testing may be not suitable for correct testing of new materials. For example, thin bands of amorphous and amorphous-nanocrystalline alloys have a specific set of mechanical properties, and as a result, their plasticity in local micro-areas cannot be evaluated. Theauthors analyzed the specific properties of a new method of mechanical testing of thin and brittle amorphous and amorphous-nanocrystalline metallic alloys by the local stress method. The drawbacks of the method were revealed. A new method of mechanical testing was proposed. It enables to determine viscosity parameters of microrupture in local areas of thin bands of brittle amorphous and amorphous-nanocrystalline metallic alloys.
