Snoek-Type Anelastic Relaxation in a Water-Quenched Ti-Nb Alloy

Abstract:

The internal friction of Ti-35.4Nb-0.05C (wt.%) was investigated using a dynamic mechanical analysis (DMA) Q800 from TA Instruments. It has been shown that a relaxational peak is observed in the water-quenched Ti-35.4-Nb-0.05C alloy on tanδ-temperature curve. The activation energy and pre-exponential factor of the peak are H_q=1.82±0.1 eV and τ_0q=1.7×10^-19±1 s, respectively. The activation energy value is a little larger than that of the water-quenched Ti-35.4-Nb alloy. The peak height is decreased compared with the water-quenched Ti-35.4-Nb alloy.
