Abstract: Metamaterials are rationally designed artificial materials composed of tailored functional building blocks densely packed into an effective (crystalline) material. While metamaterials historically are primarily thought to be associated with negative refractive indices and invisibility cloaking in electromagnetism or optics, it turns out that the simple metamaterial concept also applies to many other areas of physics namely the thermodynamics, classical mechanics (including elastostatics, acoustics, fluid dynamics and elastodynamics) and in principle also to the quantum mechanics. This lecture will review the basic concepts and analogies behind the thermodynamic, acoustic, elastodynamic/elastostatic, and electromagnetic metamaterials and differences among them. It will provide an overview of the theory, the current state of the art and example applications of various types of metamaterials. The review will also discuss the homogeneous as well as inhomogeneous metamaterial architectures designed by coordinate-transformation-based approaches analogous to transformation optics. The application examples will include laminates, thermal cloaks, thermal concentrators and inverters, anisotropic acoustic metamaterials, acoustic free-space and carpet cloaks, auxetic mechanical metamaterials, pentamode metamaterials (meta-liquid), and mechanical metamaterials with negative dynamic mass density, negative dynamic bulk modulus, or negative phase velocity. Finally an example of quantum-mechanical matter-wave cloaking will be provided.

Abstract: Twinning is known to be an important deformation mechanism in crystalline materials like metals and ceramics. Once the twin nucleates, it is normally expected that the growth of twins approaches the speed of sound in the material. However, the author and his coworkers have discovered that this process can occur at speeds many orders of magnitude lower than the speed of sound. This was found to occur both in hexagonal close-packed (HCP) structures as well as in body centered cubic (BCC) structures. More importantly, twinning in titanium alloys has been attributed to control the low temperature (<0.25 Tm) creep deformation. Given that many metallic and ceramic materials exist in HCP and BCC crystalline forms, these findings are expected to be applicable to most of these materials as well. The phenomenon of slow growth of twins has been termed time-dependent twinning. It has been suggested that this process is due to slow diffusion of oxygen atoms that occupy interstitial sites, which are displaced away from the twin/parent matrix grain boundary. In this presentation, the crystallographic and atomistic models for the diffusion of oxygen for time-dependent twinning phenomena will be presented. In addition, the effect of the microstructural parameters, such as grain size, on the time-dependent twinning phenomenon will be discussed. Furthermore, the ramifications of these findings in relation to the processing of existing metallic materials and the development of new alloys will be outlined.
