| Abstract Scope |
The observation of solidification processes in metallic alloys commonly relies on complex and large-scale instruments, such as laboratory or synchrotron X-ray ssources, which are energy-intensive and logistically challenging. We present here a technically light method for in situ observation of thin metal samples in real time during directional solidification using a simple setup that integrates one or several optical-microscopy diagnostics in a well-controlled environment. The dual-view system uses two long-distance, reflected-light optics focusing the solidification front via a beam-splitter. Both optical lines are equipped with numerical cameras with different field of views. This permits to simultaneously capture the solidification process over the whole solidification gap, and in a key region of interest. This two-scale observation mode enhances our capability to analyze the solidification dynamics of multicomponent alloys, thus offering valuable insights into the microstructural evolution of model metallic alloys of industrial relevance in response to thermal gradients and solidification speeds. |
