- •
The products obtained via HPHT sintering have high density (7.00 g/cm3), high hardness (1727HV30) and high fracture toughness (7.2 MPam1/2).
- •
The particles can be cracked under high pressure. In addition, the crystalline size has not been obviously increased during the sintering.
- •
The BSEM micrographs of cermets. They are not the classical black (white) core/grey rim structures but even distributed three colors in the BSEM images.
