Grain boundaries play a pivotal role in deformation processes especially at elevated temperatures, influencing the mechanical properties of materials. These grain boundaries are associated with a definite amount of free energy, due to a disordered structure known as grain boundary energy (GBE). The grain boundary energy, a critical parameter in this context, is challenging to measure directly due to the need for highly sensitive techniques. Instead, relative measurements, often referenced to surface boundaries, provide valuable insights into the properties and behavior of grain boundaries. Previous assessments by Udin, Frederick, Roth, and Zhevnenko have utilized zero creep experiments to evaluate surface and grain boundary energy in pure metals like copper (Cu), cobalt (Co), and nickel (Ni), as well as in Cu-Co alloys. In the context of recent research, multicomponent alloys have gained huge attention due to their outstanding combination of mechanical properties attributed to various microstructural features. 

The work focuces on the experimental calculation of grain boundary energy and significance of grain boundary energy towards the high temperature deformation of materials
