Computational alloy design

F. Tancret, I. Braems, E. Bertrand, L. Couturier

Our team, a pioneer in France in the domain, develops computer-aided alloy design methods, associating physical models (including computational thermodynamics using Calphad method and ab initio simulation) with artificial intelligence tools like data mining (machine learning) and multi-objective optimisation by genetic algorithms. These works, undertaken within academic or industrial collaborations, deal with many categories of materials (alloys based on Fe, Ni, Ti, Al, Mg; high entropy alloys HEA; complex concentrated alloys / compositionally complex alloys CCA), for a variety of applications (oil & gas / petrochemistry; energy / nuclear domain; aeronautics, automobile; micromechanics…).

The general principle of our computational alloy design method can be represented schematically as in the flow chart below. It is notably well illustrated in the PhD thesis of Edern Menou (2016) :
