Abstract

The influence of minor modifications in constitution on the temperature coefficient of resistivity (TCR) of beta stabilized titanium-base alloys is demonstrated for binary alloys with iron and nickel. Correlations with constitutional data are reviewed to show that the negativity of TCR occurs over a narrow composition range, corresponding to the threshold for 100% beta stabilization. The results for Ti-Fe and Ti-Ni alloys show that slow quenching rates leading to diffusional transformers, such as the alpha and/or omega phase-precipitation reactions, cause the TCR to increase toward positive values.
