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.
