New binder phases for the consolidation of TiB2 hardmetals
TiB2-Fe-Ni-Co-Ti-AI system The XRD trace corresponding to this composition, sintered under the same conditions as the others, is shown in Fig. 6. Although a 25 wt.% of cobalt was added to the binder, no change is observed with re- spect to the phases obtained for the TiBz-Fe-Ni- Ti-A1 system. No secondary borides are formed and a metallic ...
