Outline of Research at the Start	To cop out of stress shielding at a bone-metallic implant interface, the microstructural fabrication with {100} preferred orientation is required for reducing Young’s modulus. In this study, the microstructure of new biocompatible BCC HEA is controlled by using a hot uniaxial compression.
