| Abstract: | In the material engineering, most kinds of the applied materials are solid solution. Solid solution will change in mechanical, electrical, thermal, magnetic, and chemical properties due to different doping elements. Using the simulation calculation of first principles can preferentially select the doping method quickly, optimize the properties of solid solution and finally obtain solid solution with superior comprehensive performance. In this paper, the research methods of first principles in studying solid solution were introduced concisely. The application research statuses of first principles in electronic structure, stability, elastic constants, thermodynamics and stacking fault energy of solid solution was mainly reviewed. Finally, the existing problems of first principles in the studying of solid solution were summarized and the outlook was raised. |
