Special attention has been paid to the microstructures near the peak of the tempering curve. Mo_2C nucleared and grew along dislocation lines, martensitic lath boundaries, and some of them in situ transformed from M_3C at ferrite / cementite interface. The maximum strength in Ni10Co14 steel was achieved when the steel was tempered at 440℃ for 5 h. The strengthening of the steel was mainly attributed to the combination of the delayed dislocation recovery of the martensitic matrix and coherent precipitation of the Mo_2C particle.
