Abstract : Progress is reported on a study of the mechanical working of controlled eutectics and an exploratory program on the mechanical properties of light-metal controlled-eutectic alloys. Data obtained shows that ingots of the Al3Ni-Al eutectic (with an imperfect fiber reinforcement, i.e. a colony structure) can be drawn and hydrostatically extruded. In the other area of research progress has consisted of the production of the first heats of three magnesium base eutectic alloys. Metallographic examination and other data give evidence that it will be possible to form the desired anisotropic structure in these alloys.
