Examples of artificially grown crystals
low temperature bainite
 |
| Surface relief caused by displacive solid-state transformation in steel. Transformation is from fully austenite (face-centred cubic) to a bainitic nanostructure (in this case, body-centred cubic crystals embedded in the austenite). This surface displacement can be used to characterised the shear component of the transformation. Although the crystals are near the nm scale bulk samples of tonnage scale can be transformed to this microstructure. |
