摘要
A method for measuring a heat history, an implement for measuring a heat history, and a device for measuring a heat history, which can be used in a conveying-type or hermetically-sealed-type heat-treat furnace without wires, etc., and can be used to make simple and accurate measurements of the heating temperature and heating time over a wide temperature region, which is approximately 300−1000˚C. It is possible to estimate the heating temperature and heating time by utilizing a phenomenon in which the transmittance of an impurity-doped tin oxide film in the visible to near-infrared region changes irreversibly with respect to the received heat history.
