 | Crystal structure of austenite (a form of iron) Austenite is an allotropic form of iron. This movie shows the arrangment of atoms in a unit cell of austenite of lattice parameter approximately 0.3566 nm |
 | Ni-Ti Shape Memory Alloy Thin Film Ni-Ti Shape Memory Alloys (SMA) alloys have been attracting attention due to a number of desirable properties (shape memory effect,...) The basis of the shape memory effect is a reversible solid-state phase transformation. Ni-Ti SMA transform martensitically from B2 cubic austenite into monoclinic B19' martensite either directly or via rhombohedral R-phase. In the form of films they have also the potential for batch fabrication and, thus, Ni-Ti films are attractive materials for microfabrication and integration in micro-miniature systems composed of mechanical elements, actuators, sensors and electronics made on one chip. Applications? ...use your imagination... |
 | Temperature Induced Displacive Structural Transformations Martensitic transformation at low temperatures. Cubic iron-nickel alloy nano-particles (only half of the sample is shown in order to see the interior) undergo a martensitic transformation (first movie) from the high temperature fcc austenitic phase (red) into the low temperature bcc martensitic phase (green) (due to technical reasons the surface is green or blue depending on the orientation of the surface). The heterogeneous nucleation starts at defects like corners and grows into the interior of the nano-particle with a fraction of the sound velocity (that is, the growth velocity depends on the crystallographic direction.) with a transient mixed phase region having a needle-like pattern. The final structure is twinned and can undergo a transformation back to the original austenite structure (second movie). The sample contains one million atoms (edge length=24nm) and was simulated for 67.5ps. |

 | Shimmering Steel Surface of steel which has been heated to high temperature. After austenitising at 1200 degrees Celcius for 2 days in vaccum. Facets on the surface probably cause this shimmering effect, these could form at high temperature and correspond to the size of the austenite grains (very large ~ 5mm) |
