Strengthening and toughening mechanisms of gradient Ti(C,N)-based cermets

Journal of Materials Research and Technology
Ti(C,N)-based cermets are promising for extreme service conditions owing to their high wear resistance and thermal stability; however, their application is often limited by intrinsic brittleness and low fracture resistance. Here, a three-layer gradient Ti(C,N)-based cermet was fabricated by powder extrusion-based 3D printing followed by gas-pressure ...

Enhanced oxidation resistance of Ti(C,N)-based cermets containing Ta

Corrosion Science, 2014
(TixTa1-x)(C0.5N0.5)-Co-based cermets with various Ta contents (x=0, 0.01, 0.05, 0.1 and 0.2) were oxidized at 900°C for 48h in static air. A parabolic rate law, which is indicative of the formation of a protective oxide layer, was observed for all samples.

Sintering of Ti(C,N)-Based Cermets: The Role of Compaction

Materials and Manufacturing Processes, 1995
Different compaction processes were employed in studying the effect of green state on the sintering of TiC-TiN-Ni-Mo2C and Ti(C0.3N0.7)-Ni-Mo2C cermets. Specimens were uniaxially pressed and some being subsequently compacted by cold isostatic pressing. Liquid and solid phase sintering was carried out in nitrogen atmosphere.

Microstructure and Properties of the Cermets Based on Ti(C,N)

International Journal of Refractory Metals and Hard Materials, 2009
Abstract Effect of Mo and Mo 2 C on microstructure and properties of Ti(C, N)-based cermets was investigated in this paper. The results shown that Ti(C, N) grain diameter and thickness of the rim can be reduced by adding the weight percentage of Mo from 5 to 10, and Ti(C, N) grain can be wetted by Ni–Cu–Mo liquid so as to getting small contiguity of ...

Preparation of Ti(C,N)-Based Cermets

Advanced Materials Research, 2010
Ti(C,N) solid solution were prepared at 1450°C and 1atm nitrogen pressure and the effect of the ways of adding nitrogen on the mechanical properties and microstructures of Ti(C,N)-based cermets were investigated. XRD and FESEM were employed to characterize the as-prepared Ti(C,N)-based cermets.

Microstructure of hot-pressed Ti(C,N)-based cermets

Journal of the European Ceramic Society, 2002
Starting from commercial nanosize TiN and carbon black powders, this study set up a synthesis of fine and pure Ti(C,N) powders. The best experimental conditions were found using a mixture TiN+10 wt.% of C processed at 1430 C for 3 h under flowing Argon.
