Properties of Materials Quenched from the Liquid State.
Abstract
Metal alloys and refractory oxides have been quenched (splat cooled) from the liquid state at ultra-high rates using a wide range of techniques. The alloys have been quenched by the standard shock-tube method, while oxides were quenched using laser methods or with plasma spraying. The rapid quench permits access into metastable regions of the phase diagram, thus yield ultra-high supersaturation. The earliest regime of precipitation reactions are able to be detected, and, thus, a linear spinodal process has been determined in several alloys. Liquid quenching is useful for studies of phase transformation, since the system can be obtained in highly metastable states. Small-angle x-ray and neutron scattering and transmission electron microscopy were used in this study. (Author)
