Abstract

In the area of wire wrap, there is a relationship between the degree of cold working and the temperature of recrystallization. As the amount of cold work increases, there is a decrease in temperature at which recrystallization occurs. For this to occur there must be points of nucleation in the metal. The ions must be mobile to improve the probability that a certain number assume the lattice positions of a few strainfree unit cell which acts as a nucleus.

Wire Wrapping Tool

In the area of wire wrap, there is a relationship between the degree of cold working and the temperature of recrystallization. As the amount of cold work increases, there is a decrease in temperature at which recrystallization occurs. For this to occur there must be points of nucleation in the metal. The ions must be mobile to improve the probability that a certain number assume the lattice positions of a few strainfree unit cell which acts as a nucleus.

Discontinuities, grain boundaries and regions of stress provide nucleating centers. The process of wire wrapping increases the number of the centers. By raising the temperature, ion mobility is increased and the probability of the formation of strainfree nuclei is improved. The total energy of a molecule: E(total) = E(Electronic) + E(Vibration) + E(Rotation)

In this formula the E Rotation can be neglected in the area of wire wrap. The electronic heat conduction process is roughly one hundred times as effective as the lattice vibration process. Therefore, applying an AC through the secondary coil 10 causes a rapid oscillating transfer of electrons. Such also increases the lattice vibration in wire 11, speeding up the formation of strainfree nuclei.

In operation, wire 11 is inserted in the end of the barrel of gun 12, and out through aperture 14. A half-turn is then made around headed pin 15. As bit 16 is rotated to effect a wrap, the wire is cut to a specific length and heated during the wrappin...
