Eutectic alloys have achieved a central position in the history of human civilization, from cast irons in agricultural society to ceramic composites in aerospace industry. Even so, eutectics are losing competitiveness among advanced engineering materials due to their inherent brittleness and unsatisfactory phase/interface stability at elevated temperatures and in chemically-aggressive environments.
Recently, to address these challenges, researchers have developed novel and innovative solutions, among them, ternary and higher-order (multi-principal-component) eutectics as well as new solidification techniques such as laser-aided processing that allows control of the microstructure to a nanometric level. These recent efforts have raised a number of questions concerning the physics of highly-non-equilibrium pattern formation; multi-step phase transformation pathways; dopant/impurity segregation at interfaces; microstructural hierarchy; and multi-functionalities. It is our objective in the seventh installment of the Directionally Solidified Eutectics Conference (DSEC) to address these pertinent topics, evaluate the state-of-the-art, and identify future directions in the context of recent advances.
As alluded to above, the Istanbul meeting will focus on several topics that span fundamental to applied science including, but not limited to,
