Four identical steel samples were alloyed with W, Mo, and with W + Mo in various proportions. It was found that introduction of either of tbese alloying additions into the system results in the formation of a carbide of the type of Me/ sub 23/C/sub 6/. Using a W/Mo ratio of 3: 1, in addition to the above carbide, the Laves phase is also obtained after aging at 750 to 800 deg C and an extended heat treatment. With a W/Mo ratio of 1: 1, the Laves phase is formed after aging the alloy for 100 hours at 650 deg C together with a facecentered cubic interstitial structure. Any Nb present in the steel forms primarily the carbide NbC. (TTT)
