Abstract

A new apparatus for making in situ measurements of changes in the electrical resistivity accompanying phase transformations in metallic alloys is presented. Measurements can be made in vacuum or inert gas at annealing temperatures as high as 1500 K. The long-term thermal stability is better than ±0.3 K. The measurement circuit is stable to better than 0.01% over any time scale. This apparatus provides a relatively simple and inexpensive means for obtaining high temperature resistivity measurements on very brittle samples.
