PROBLEM TO BE SOLVED: To provide a metal part such as an engine turbine blade for an aircraft in which high cycle fatigue life is improved. SOLUTION: This high elasticity part such as the engine turbine blade for an aircraft is formed of base metal having the high elasticity crystal direction aligned in a main direction of the engine turbine blade, that is the radial direction. The base metal is alloy of Ni, Fe, Ti, Co, Al, Nb, or Mo base. By thus arranging the high elasticity direction of the base metal in the main direction, high cycle fatigue life is improved.
