DESCRIPTION:DMSE Master’s Thesis Seminar \n\n \n\nEffect of cooling rate 
 during solidification of Aluminum - Chromium Alloy \n\n \n\nGautham Muthus

 n of alloying elements in aluminum casting and designing new processing pr
 actices are supported by an enhanced understanding of the thermodynamics a
 nd kinetics of solidification at industrial scales. While the behavior of 
 eutectic forming elements such as copper has received a lot of attention\,
  the interactions of peritectic-forming elements such as chromium is under
 studied. We herein use a time-dependent nucleation model for the calculati
 on of the incubation time of nuclei in the liquid. This characteristic tim
 e is computed at various temperatures\, and the results are presented in t
 he form of a time-temperature diagram. Liquid phase thermodynamics of dilu
 te compositions in the aluminum-chromium system are experimentally informe
 d using the electrochemical potential difference method. Thermodynamic dat
 a obtained from these investigations are used to inform physical propertie
 s of the aluminum-chromium melt. The aforementioned time-temperature diagr
 ams are recalculated using experimental data and theoretical cooling rates
  for phase selection are calculated. Critical cooling rates calculated fro
 m the model are applied to industrially relevant practices such as DC cast
 ing and Twin roll casting.\n\nThesis Supervisor \n\nAntoine Allanore\, Ass
