Rapid e-beam heating for measuring thermodynamics of metastable materials
Abstract
A line-source electron-beam system has been used to heat thin surface layers of metastable phases at a rate which precludes solid-state transformation to stable phases, thus permitting the observation of melting transitions normally missed with slow heating. A detailed example of a new approach to this method is shown for metastable icosahedral Al-Re and crystalline Al6Re.
