Mechanical spectroscopy measurements have been extensively used in the last decades to obtain information about many aspects of the behavior of solutes in metallic materials. Metals of body-centered cubic lattice that contain heavy interstitial eleme

Elastic softening in the paraelastic phases of Ba_{1−x}Sr_{x}TiO_{3} is largest near the transition temperatures and decreases on heating smoothly over extended temperature ranges. Softening extends to the highest measured temperature (850 K) for B

The elastic softening occurring at pure ferroelectric transitions is of piezoelectric origin, and, neglecting fluctuations, can be written as the tensor product [1] Ds^piezo = d+.(1/e).d (1) where s is the compliance, d is the piezoelectric coefficie

A mechanical spectroscopy study of Cu-Zr-Al bulk metallic glasses, was performed with two types of equipment: a Kê-type inverted torsion pendulum and an acoustic elastometer, working in the frequency ranges of Hz and kHz, respectively, with a heatin
