About this Materials Science article
TiN/Al2O3 composites and graded laminates thereof consolidated by spark plasma sintering by Zhijian Shen; Mats Johnsson; Mats Nygren is a Materials Science article available to read on EtoBox.
A rapid consolidation process named Spark Plasma Sintering (SPS) has been applied to compact duplex TiN/Al 2 O 3 composites and graded laminates thereof. Fully or nearly fully compacted samples were prepared at 1500 C with a holding time of 3 min under a pressure of 75 MPa. The unusually high grain-growth rate of Al 2 O 3 occurring in monolithic Al 2 O 3 at this sintering temperature is prevented by the addition of TiN particles. Crack-free graded laminates with distinct interfaces between layers were prepared by loading samples inside the die, both symmetrically and asymmetrically. The observed mechanical properties, e.g. hardness and fracture toughness, are related to the microstructural features of the compacted samples.
