چکیده
The structure and strength of Al x Si-2wt.%Cu (x = 15, 17 20 wt.%) alloys obtained by directional solidification at a rate 0.1 0.8 mm/s are investigated. It is shown that the tensile increases with an increase in due to decrease size eutectic silicon transformation its crystal flake into fine-fiber one. In addition, there was share intermetallic phase, exceeding reduced amount α-Al phase. An content samples during does not lead change strength. At higher solidification, reduction Keywords: aluminum alloys, eutectic, structure,
