Abstract
Unique in-situ electric resistivity measurement was utilized to identify microstructural changes in ultra-fine grained commercially pure titanium and Ti-6Al-7Nb alloy. Both materials were prepared by equal channel angular pressing. Changes in resistivity evolution during in-situ heating were compared to scanning electron microscopy observations. Both materials are stable up to 440°C. Further heating at rate 5°C/min causes recovery and recrystallization of UFG structure. At 650°C the microstructure is fully recrystallized. High resolution in-situ electric resistivity measurement is capable of detecting recovery and recrystallization in UFG CP Ti and Ti-6Al-7Nb alloy.
