Effects of Mo2C on Microstructures and Comprehensive Properties of Ti(C, N)-Based Cermets Prepared Using Spark Plasma Sintering

Molecules
Ti(C, N)-based cermets are problematic in practical production applications due to their brittleness. To improve this defect, Ti(C, N)-based cermets were prepared under different sintering environments using a spark plasma sintering (SPS) device with ...

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

Materials and Manufacturing Processes, 1995
Abstract Different compaction processes were employed in studying the effect of green state on the sintering of TiC-TiN-Ni-Mo2C and Ti(C0.3N0.)-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. Green state porosity,

Ti(C,N) based cermets with Cu-containing binder phase

2021
Ti(C,N)-Co/Ni-based cermets were prepared with various Co/Ni ratios and addition of Cu to the starting formulation. The powder formulations also contained tungsten and molybdenum carbides in various proportions while both the [W] and [Mo] concentrations were kept identical. Samples were prepared with either 9.7 or 16.4 vol% binder phase.

Denitrification of Ti(C,N) based cermet during powder mixing process

Journal of Materials Science, 2002
Changes in the nitrogen content of Ti(C,N)-based cermets during powder mixing and sintering processes were investigated and the denitrification mechanism was re-evaluated. The denitrification of N-containing cermets occurrs mainly during the powder mixing process, and is relatively small during sintering periods. Denitrification during powder mixing is

Ultrafine (Ti, M)(C, N)-based cermets with optimal mechanical properties

International Journal of Refractory Metals and Hard Materials, 2011
Abstract A tough and strong cermet with the composition (Ti,20M,0.2V)(C,N)-16M-20Ni/Co (M = W,Mo) was prepared by mixing WC and Mo 2 C with ultrafine (Ti,M)(C,N) powders, and then, processed via a conventional P/M technique. It has an ultrafine and distinct core/rim structure, resulting in excellent mechanical properties: bending strength of 2210 MPa,

Spark plasma sintering properties of ultrafine Ti(C,N)-based cermet

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2004
Ultrafine Ti(C,N)-based cermet was sintered by SPS from 1050°C to 1450°C and its sintering properties, such as porosity, mechanical properties and phase transformation, were investigated by optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and differential scanning calorimeter (DSC). It is found that the spark plasma

The microstructure of ultra-fine grade Ti (C, N)-based cermets

International Journal of Machining and Machinability of Materials, 2006
The microstructure of ultra-fine grade Ti (C,N)-based cermets was examined by X-Ray Diffractometry (XRD), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). A kind of new core/rim structure and an unknown compound based on Ni, Mo, W and C were detected and their formation mechanisms were discussed.

Microwave sintering of Ti(C, N)-based cermet cutting tool material

Ceramics International, 2018
Abstract A Ti(C, N)-based cermet cutting tool material with satisfactory properties was fabricated in an energy-efficient way by microwave sintering. The effect of microwave singtering process and the component ratio of carbide (WC, Mo 2 C) on phase composition, microstructure and mechanical properties were studied. The cermet containing 5 wt% WC and

Ti(C,N)-based Cermets For Sawblades: Preparation, Properties, Testing And Upscaling

World PM2022 Proceedings, 2022
A Ti(C,N)-based cermet grade for sawblade production was developed, targeting performance of commercially available grades. Firstly, laboratory investigations focused on commercial cermets compositions and properties. Subsequently, a variety of laboratory grades were prepared and characterised (HV10, KIC, LOM and SEM, HC, MS, CGHE, DTA, XRF).
