The microstructure of alloys, which is influenced by structural phase transformations, strongly affects their mechanical properties. Precipitation hardening, a well-known phenomenon in alloy development, involves the evolution of precipitate morphology leading to complex 3D shapes. Understanding this phenomenon is critical to improving the strength of industrial alloys. To get a handle on the complex and nonlinear nature of microstructure evolution, the phase field method has proven to be a powerful computational tool. It uses two field variables, the concentration (a conserved variable) and the order parameter (a non-conserved variable), which are determined by the Cahn-Hilliard and Allen-Cahn equations. In her talk, Prof. Zapolsky will present the phase field approach and its application in describing precipitation kinetics and crystal growth in metal alloys.

Prof. Hélèna Zapolsky is a renowned theoretical physicist and professor at the University of Rouen, France. She is an expert in the field of theoretical solid state physics and has made significant contributions to the understanding of pattern formation and the kinetics of phase transformation in various materials. In her research, she uses mathematical and computational methods to model non-equilibrium dynamics in complex systems.

As a visiting professor at E3, prof. Zapolsky brings her knowledge and expertise in the field of theoretical solid-state physics.
