Abstract
The methods of mechanical treatment of ingots giving rise to formation of internal texture of metal are widely used. On the other hand, it is well known that the flow of metallic melt can results in dark streak pattern, clear observed in an ingot. In the present work the influence of directional flow of metallic melt on physical properties of the solid metal was studied. The objects for investigation were copper, aluminum and gray cast iron. The metal solidified after the directional flow was found has improved (7 to 23 %) hardness and better resistance to attrition. The hardness of the check samples, crystallized without of directional flow, has data scattering less then 2% and their resistance to attrition - less then 5%.
