Abstract : This invention relates to a method for separating trialuminum nickelide fibers from an aluminum matrix. More particularly, this invention concerns itself with the electrolytic production of trialuminum nickelide fibers from an aluminum/trialuminum nickelide two phase composite matrix. Considerable interest has been developed in the utilization of aluminum nickel fibers. These fibers find application for use as catalysts, obfuscating agents, and as components for microelectronics. Their wide application results from the fact that inclusion of a controlled eutectic alloy of trialuminum nickelide within an aluminum body provides an effective means for giving high tensile strength enhancement to the aluminum body. The alloy is grown within the aluminum body as an aligned microstructure in the form of whiskers by a technique referred to as unidirectional solidification. In addition to providing improved tensile strength, the whiskers of trialuminum nickelide are useful, in and of themselves, in a variety of industrial and military microelectronic applications provided they can be removed undamaged from the aluminum matrix in which they are embedded.
