On the complementarity between resistivity measurement and ultrasonic measurement for in-situ characterization of phase transitions in Ti-alloys

We present the results of in-situ characterization of the phase transitions in metastable beta-Ti alloy Ti5553 by contactless laser-based resonant ultrasound spectroscopy method and electrical resistance measurement in a four probe configuration. Phase transformations were studied during continuous heating from the room temperature to 700 degrees C with various heating rates. We showed that both methods provide complementary results and can be successfully used for observation of phase transitions in metastable beta-Ti alloys. (C) 2018 Elsevier B.V. All rights reserved.
