The invention belongs to the field of casting component design and preparation, and discloses a nickel-cobalt alloy synergistically strengthened and toughened by means of microelement interaction and preparation, the nickel-cobalt alloy is Ni [50-x] Co [50-x] Ti [x] C [x], x is 0.3-0.7; in the nickel-cobalt alloy, the atomic percentage of the Ni element and the atomic percentage of the Co element are both (50-x)%, and the atomic percentage of the Ti element and the atomic percentage of the C element are both x%; and by introducing the Ti element and the C element, the strength and toughness of the nickel-cobalt alloy can be improved at the same time. According to the invention, Ti and C elements with proper interaction strength are selected, and the contents of solute elements Ti and C are controlled, so that obvious element segregation characteristics are generated in the alloy solidification process, and other phases are not formed while element clusters are formed, that is, under the condition that a singl
