Abstract
A metal structure includes, by mass %, Fe: 10% to 30%; S: 0.005% to 0.2%; and the balance consisting of Ni and unavoidable impurities, in which a maximum grain size of the metal structure is 500 nm or less. The metal structure preferably has one or more of a stress relaxation rate of 10% or less, a lattice constant of 3.535 Å to 3.56 Å, a yield stress of 1500 MPa or more, a Young's modulus of 150 GPa or more and a Vickers hardness of Hv 580 or more.
