Abstract: The dynamic shear modulus and compliance of the dynamic glass transition were investigated in two metallic glasses (Pd40Ni40P20 and Zr65Al7.5Cu17.5Ni10). Isothermal measurements over four frequency decades enable the determination of shape parameters for the proper glass transition. The real part of the dynamic shear compliance shows a step height of approximately a factor of 2.6 for Pd40Ni40P20, comparable to low molecular weight glass formers or the segmental mode as part of the glass transition in high molecular weight polymers. The frequency dependence of the imaginary part of the shear compliance at the high frequency side of the peak shows an exponent near the Andrade value of 1/3.
