The Traditionally, MP35N (containing both cobalt and nickel) mechanical properties of this alloy at room temperature and 77 is described as a multiphase cobalt nickel alloy because some K are examined. The cold-rolled and aged MP35N produces a cobalt-nickel alloys are work-hardened by formation of the hardness of 5650 MPa and yield strength of 2125 MPa at room stress-induced hexagonal-close-packed (hcp) phase in temperature. At 77 K, the yield strength reached 2500 MPa platelet form within fcc matrix [2]-[4]. However,
