摘要：

The structural changes occurring during the tempering of a 12%Cr-6%Mo-10%Co-0.1 %C steel have been investigated. It has been shown that an intermetallic compound R-phase is responsible for the marked secondary hardening but that the carbides M2X and M6C are also precipitated. The R-phase contained iron, chromium and molybdenum but little or no cobalt. By determining the orientation relationship between R-phase and ferrite it has been shown that the precipitation of R-phase in ferrite is theoretically favourable. © 1969.
