The doping effect of the bubble formation oxide on the recrystallization of molybdenum wire was investigated. Five different wires of 1 mm in diameter were prepared through sintering, swaging, and drawing processes.
Each wire was doped with various amounts o%f potassium (K) plus silicon (Si), i.e., 0, 0.028, 0.14, 0.28, and 0.49 by weight percent, and annealed for 30 minutes at given temperatures.
To understand the overall recrystallization phenomena, changes in hardness and in optical microstructures were examined.
Transmission electron micrographs were taken for the specimens in the as-drawn state and at the beginning of the decrease in hardness.
