Keywords: High entropy alloys (HEAs), Bio metallic materials, microstructure, Young’s modulus Abstract.
Introduction High entropy alloys (HEAs) are defined by their mixing entropy, DSmix, and have recently attracted significant attention as a group of materials distinct from conventional metallic materials [1-4].
They exhibit particularly high strengths and are expected to be used as new refractory materials [5].
In general, metallic materials with a high yield strength tend to have a high Young's modulus, and it is considered that high-strength materials, such as TiZrNbTaMo bio-HEAs, also have a high Young's modulus.

It can make full use of the two materials’ nature.
The results show that the neotype anchor system can make full use of the materials’ nature and is in good working order.

Introduction SOFCs are type of fuel cells which use a solid oxide as the electrolyte material.
SOFC comprises three main parts made of ceramic materials: porous anode, gas-tight solid electrolyte and porous cathode.
This would solve many materials science problems and significantly increase the life of the SOFC.
