Texture of directionally solidified Al--CuAl/sub 2/ eutectic alloy

Technical Report ·
DOI:https://doi.org/10.2172/6807875· OSTI ID:6807875
An experiment was conducted to determine the texture of an Ai-CuAl/sub 2/ eutectic alloy unidirectionally solidified at 12.9 ..mu..m/s under a temperature gradient of 70.7/sup 0/C/cm. Directional solidification produced a parallel well aligned microstructure with an interlamellar spacing of 2.73 ..mu..m. The lamellae exhibited a strong preferred orientation or texture. An x-ray diffractometer method was used to obtain the data and pole figures corresponding to each of the two solid phases were plotted. The pole intensities were represented in terms of ''times random'' units.
