| 英文摘要 | Temperature-coefficient of resistivity (TCR) is positive for most metallic materials but negative for semiconductors. Since a Ti-Nb-based titanium alloy exhibits a negative TCR, this inspires us to tune its TCR from negative to positive by a decomposition-induced compositionally-modulated dual-phase microstructure. Here reports a continuously tunable TCR obtained by aging treatments at 723 K. The results demonstrate that a near-zero TCR over a wide temperature of 350 K is available via 0.5 h aging while its TCR varies almost linearly with the volume fraction of alpha" phase in the plate-like modulated microstructure. Aided by a mixture rule modeling, the tunable TCR can be quantitatively characterized by the beta + alpha" dual-phase compositionally-modulated microstructure induced by aging treatment. These findings provide a new avenue for exploring novel temperature-independent properties by tuning spinodal decomposition. (c) 2023 Elsevier B.V. All rights reserved. |
