Abstract
A unique feature of the electrical resistance accumulation property of cyclically deformed polycrystalline constantan foil can be directly used to develop the fatigue life gauge. However, the intermediate annealing heat treatment during the cold rolling process of foil forming has a significant effect on the cumulative electrical resistivity of foil. Based on the orthogonal experiment design, in this paper, 4 kinds of polycrystalline constantan foils have been prepared by combining different levels of annealing temperature and time. Through a series of fatigue experiments carried out in the laboratory, it is demonstrated that the foil electrical resistance accumulation rate increases with the increase in the annealing temperature while the electrical resistance accumulation rate decreases with the increase in the annealing time. Subsequently, the optimal annealing temperature and time have been achieved.
