Abstract
Various preparations and uses of single crystal metals are discussed. We briefly review (i) preparation methods of single crystal metals such as growth from melts, epitaxial deposition in vapors and solutions, and abnormal grain growth in solids and (ii) uses of single crystal metals according to their produced shapes (“bulk” vs “film and foil”). We pay special attention to recent advances in the preparation of large area single crystal metal foils and their potential uses.
Highlights
A grain in metallurgy is a small or microscopic single crystal, which has a periodic arrangement of atoms
Most metals in general use are polycrystalline, consisting of grains separated by grain boundaries (GBs), whereas single crystal metals have a single grain throughout the entire sample and have no GBs
The mechanics of single crystal metals differ from polycrystalline metals because the strength of a metal is strongly related to the size of the grain
