Abstract
To study the melting and solidification process of a metallic crystal, an in situ heating device for real time X-ray topography has been newly developed and used for the case of a pure aluminium single crystal. Solid-liquid interface remains macroscopically flat and facet growth is not seen. The perfection of slowly grown crystal is better than that of rather rapidly grown one.
