dc.description.abstract	Electrical discharge machinable ceramics provide an alternative machining route independent on the material hardness which enables manufacturing of customized ceramic components. In this study a composite material based on an alumina/zirconia matrix and an electrically conductive titanium nitride dispersion was manufactured by hot pressing and characterized with respect to microstructure, mechanical properties and ED-machinability by die sinking. The composites show a combination of high strength of 700 MPa, hardness of 17-18 GPa and moderate fracture resistance of 4.5-5 MPa√m. With 40 kS/m the electrical conductivity is sufficiently high to ensure ED-machinability.	en
