Abstract

Conditions of gauging true microhardness of thin ribbons of amorphous metallic alloys (AMA) taking into account of their depth are established. For the first time the indentation method was approved for an assessment of crack resistance of AMA. The behavior of parameter K_1c was found in the temperature interval of viscous -brittle transition down to the beginning of volumetric crystallization of AMA. The estimation method of temperature of viscous -brittle transition is offered at the microindentation of annealing ribbon on an elastic substrate.
