Studying deformation behavior of the alloy Ni3Ge as a base for production of novel high-temperature indutrial materials in aerospace engineering (2014-2015)

supported by the Russian Foundation for Basic Research

Project goal

Discovery of the physical mechanisms forming the basis of deformation behavior of intermetallic alloy Ni3Ge under different temperature and force conditions.

Project partner

Department of Materials Science & Metallurgy University of Cambridge (Great Britain)

Budget

750 000 rubles

Anticipated project results

  • Based on the electron microscopy study, experimental data on the evolution of the dislocation structure of deformed samples will be obtained, and the parameters of the dislocation structure will be defined.
  • Original approach to the conduction of thermal-activation analysis for alloys with superstructure L12 having abnormal temperature dependence of mechanical properties will be developed.
