2004 - ASM Fellow “For pioneering developments in the understanding and modeling of microstructure evolution during materials processing related to solidification processing, and for research leading to innovative microstructure simulation tools on technological products.”

Overview

Michel Rappaz is affiliated with the École Polytechnique Fédérale de Lausanne in Switzerland. Their research focuses primarily on engineering and materials science, with a notable emphasis on materials chemistry, aerospace engineering, and mechanical engineering.

The main topics explored in their work include:

Solidification and crystal growth phenomena
Aluminum alloy microstructure properties
Metallurgical processes and thermodynamics
Quasicrystal structures and properties
Material dynamics and properties
Additive manufacturing materials and processes
Additive manufacturing and 3D printing technologies

Rappaz has contributed to various journals, with frequent publications in:

Metallurgical and Materials Transactions A
International Materials Reviews
Materials
Journal of Alloys and Metallurgical Systems
IOP Conference Series Materials Science and Engineering

Some of their recent papers include:

"Solidification of Metallic Alloys: Does the Structure of the Liquid Matter?" (2020) published in Metallurgical and Materials Transactions A
"Does MCWASP still follow Moore's law? Forty years of advances in microstructure modeling" (2020) published in IOP Conference Series Materials Science and Engineering

Though Rappaz was not the primary author, relevant coauthors frequently collaborating with them are:

W. Kurz
David J. Fisher
J. Zollinger
J. Valloton
Abdoul-Aziz Bogno

Michel Rappaz has also contributed to book publications released by Trans Tech Publications and Trans Tech Publications Ltd. eBooks. These include the "Fundamentals of Solidification 5th Edition" and related solution manuals, published in 2023.

Their research has been cited with attention to both theoretical and applied aspects of solidification and microstructure evolution in metallurgical processes. Recognition includes the ASM Fellow award in 2004 for contributions to the understanding and modeling of microstructure evolution during materials processing.
