Understanding the impact of thermo-solutal convection during alloy solidification is of central
importance in the casting industry. Convective flow generated from density variations in the …

We present a review of recent in situ experimentation studies of solidification front patterns
and microstructures in alloys. Front-tracking diagnostics and real-time observation methods …

This work is dedicated to the advanced in situ X-ray imaging and complementary ex situ
investigations of the growth mechanisms when silicon solidifies on a monocrystalline seed …

Synchrotron X-ray imaging has been used to examine in situ the deformation of dendrites
that takes place during the solidification of a nickel-based superalloy. By combining …

The 3-D morphology of the primary silicon particle (PSP) in a hypereutectic Al-20 wt% Si
alloy was characterized using synchrotron X-ray tomography. It was found that the most …

The structure and origin of twin defects have been studied over the past half-century.
Recently, there has been renewed interest in investigating the mechanisms by which twin …

The grown-in dislocation dynamics and interaction mechanisms with growth twins are
investigated in-situ during the directional solidification of silicon crystal. The melting …

Directional solidification from mono-crystalline Si seeds having different orientations along
the growth direction is studied. Due to the frequent twinning phenomenon, new grains soon …

The growth structure of photovoltaic multicrystalline silicon formed by directional
solidification presents a high fraction of Σ3 and higher order twins. Previous studies …

The growth of multi-crystalline silicon ingot for Photo-voltaic application has been done
using an optimized directional solidification process. Two Directional solidification furnace …
