Abstract : The phase equilibria investigations described in this report are in direct support of Air Force sponsored cutting tool research programs. The results reported here are expected to serve as direct guidelines for the selection of possible candidate cutting tool alloys. Since the making of carbide cutting tools with refractory metal binder phases must depend on high temperature fabrication techniques, it is mandatory that thermochemical equilibria be attained and maintained within the proposed alloys to guarantee the physical and mechanical integrity of the cutting tools. The investigation of the high temperature phase equilibria of possible alloy combinations is, therefore, a prerequisite for the fabrication of even test alloys. (Author)
