“…However, for metallic glasses the dynamical relaxation can be measured only by mechanical analysis where the shear modulus and the mechanical loss are measured as a function of temperature and frequency. The structural relaxation can be observed by various SRA measurements of a variety of physical properties, such as viscosity, 611) positron annihilation lifetime, 12,13) enthalpy, 11,1416,19,20) and volume 11,1720) as well as mechanical properties. 21) Structural relaxation was reported by Fan 14) by means of enthalpy relaxation in a temperature range just below T g for Pd 43 Cu 27 Ni 10 P 20 BMG.…”
