  Recent theoretical and practical research has focused on multi-component High
Entropy Alloys (HEAs), which have superior mechanical and functional properties
than standard alloys based on a single major element, thereby establishing a
new field. A multi-component HEA contains five or more primary elements at
concentrations ranging from 5 to 35 atomic percent. We examined the
microstructure and mechanical properties of TiVCoNiMn2 HEA. The mixing enthalpy
and other thermodynamic parameters were determined using Meidma's model.
TiVCoNiMn2 exhibits a mixing enthalpy of -15.6 kJ/mol and an atomic radius
mismatch of approximately 10.03%. HEA is derived from both hydride and
non-hydride-producing elements. This could be a useful hydrogen storage
material. The hydrogen absorption/desorption capabilities of these HEAs are
promising.
