## Abstract Commercial purity Alβ40% Cu alloys were directionally solidified under a constant temperature gradient of 9 K/mm and growth rate (R) varying from 8 to 305 ΞΌm/sec. Cellular structure was obtained with a single primary CuAl~2~ rodβlike dendrite in the cell centre and a fannedβout eutectic
## Abstract The influence of various alloy elements on tensile strength of the eutectic, directionally solidified superalloy 73 C was determined. The tensile properties of the base alloy had been increased by Al, Y and C as alloying elements, while Ni and Ti showed a decreasing effect (alloy soften
