Abstract
A high pressure Mössbauer spectrometer for the 93.3keV resonance in67Zn has been used to investigate Zn metal and two Cu−Zn alloys with Zn concentrations of 41.9at% and 48.0at% at 4.2K and pressures up to ∼58kbar. For Zn metal the c/a-ratio plays an important role to describe the change of the Mössbauer parameters with pressure. Most striking is the increase of the recoil-free fraction by a factor of ∼3. In the brass alloys a new phase is observed at 4.2K and high pressures which we tentatively identify with a martensitic α1-phase.
