Mechanical Response and Deformation of Ni3Al7 Alloys Using In-Situ Transmission Electron Microscopy Compression and Nanoindentation
Mechanical response and deformation of Ni3Al7 alloys have been characterized using in situ transmission electron microscopy (TEM) compression and nanoindentation experiments. It has been found that the elastic modulus of Ni3Al7 is 32.69–44.84 GPa, while its hardness estimated by nanoindentation is between 4.49 to 7.21 GPa. Moreover, evidence of strain hardening behavior of the Ni3Al7 alloy has been observed. In addition, the effect of size on the compressive and bending behavior of the pillared structures is also discussed. The present results provide necessary information needed for better understanding of the mechanical properties and deformation of Ni3Al7 alloys.
