Outline of Final Research Achievements

A nickel foil and a nickel alloy foil were produced by electroplating. It was confirmed that the recrystallization temperature of the nickel alloy foil was higher than that of the nickel foil. Cyclic loading tests were performed and it became clear that the stress can be measured from the density and crystallographic orientation of the grown grains of the nickel foil under the ambient temperature of 250 ℃.　Although the grain growth of the nickel alloy foil could be confirmed at the ambient temperature of 350 ℃, we could not derive the calibration equation for measuring the cyclic stress.
