Furthermore, it might be manufactured by classic ceramic technologies and even colloidal processing. To achieve high toughness and strength, it is necessary to have a perfect mix of hard phase and binder, which is mainly achieved by ball milling. Mechanical and physical properties as well as results on different tribological and application-oriented machining tests are presented. The results have been compared with results obtained with NbC grades with Co and Fe3Al binders as well as with pure binderless hot-pressed NbC and SPS sintered Nb2O5. T2 - ICCCI 2018 - 6th Int.

Homogeneous microstructures with relative densities larger than 99% of the theoretical density have been achieved by gas pressure sintering in argon atmosphere. However, mechanical properties like hardness and strength were slightly decreased due to precipitation of free carbon.
