Abstract
A process for the production of trialuminum nickelide fibers which involves the utilization of an oxalic acid-hydrogen chloride mixture for separating the fibers from a solid, two-phase, composite matrix of aluminum and trialuminum nickelide fibers.
Claims2
A process for separating trialuminum nickelide filaments from a solid, two-phase, composite matrix containing aluminum and trialuminum nickelide filaments which comprises the step of placing an ingot of the said aluminum composite into a leaching solution composed of 2 percent by weight oxalic acid and 0.09 percent by weight hydrogen chloride for a period of time sufficient to effect the separation of said trialuminum nickelide filaments from said matrix.
