Abstract
Considered is the procedure for evaluation of mechanical properties of small-sized specimens based on determination of microhardness by the depth of penetration of Berkovich indenter in case of continuous indentation. Technical capabilities of this procedure have been assessed by evaluating the properties of γ-TiAl joints made by diffusion bonding. Statistical data on local distribution of microhardness were obtained, and values of Berkovich hardness, Young modulus and ductility coefficient of structural components within the zone of the diffusion bond have been determined.
