摘要：
The ultra-strength alloy steel with high content of Co and Ni is typical tempering martensitc steel, and the secondary hardening is accomplished by the precipitation of fine scale alloy carbides with black-white contrast until peak-hardening. The crystal structure of precipitates was well determined as M2C with hexagonal by micro-beam diffraction. Observing in HREM, M2C carbides were shown coherent with the ferrite matrix completely and have their own structure.
