Controlling the emergent microstructures in template-directed eutectic solidification for optical applications
… an external tuning knob could be the rate of solidification of eutectic alloys. In a eutectic system, multiple solid phases emerge, often in regular structures, as the melt solidifies and these phases could comprise of metals, organics, salts, ceramics, semiconductors, and polymers. The …

Instationäre Erstarrung eutektischer Al-Si-Legierungen
Solidification research has supplied an increasing contribution in the understanding of the relation between process-based solidification parameters (e.g. velocity, temperature gradient) and microstructure parameters in cast alloys (e.g. lamella distance, dendrite spacing). This is due to the …

Micromechanical phase-field model and simulation of eutectic growth with misfit stresses
Precise understanding of eutectic solidification and its controlling parameters is crucial in characterizing of many metal products. Numerical simulations are required to predict the formation of eutectic lamellae and the resulting microstructure which, in turn, determines the macroscopic …

MESOSCALE MICROSTRUCTURE EVOLUTION, RELIABILITY AND FAILURE ANALYSIS OF HIGH TEMPERATURE TRANSIENT LIQUID PHASE SINTERING JOINTS
… The complicated process of IMC formation through eutectic solidification and the extensive number of parameters affecting the final microstructure make it impractical to experimentally study the effect of each factor. In this work, phase field modeling of the microstructure of TLPS materials …
