Influence of value of the criterion of blunting on the selection of the brand of hard alloy and optimum cutting speed when turning austenitic steel [PDF]

MATEC Web of Conferences, 2017
A mechanisms of wear carbide tool when turning of austenitic steel 18-8 by cutters from firm hard-alloys of various groups (WC-Co, TiC-WC-Co, TiC-TaC-WC-Co) were studied.

Investigation of the tribological behaviour of WC/TiC based cermets in contact with Al2O3 alumina under high temperature [PDF]

Journal of the Mechanical Behavior of Materials, 2018
WC/TiC-based cermets are, generally, considered as potential alloys widely used in hot rolling industry because of their interesting properties, namely high resistance to wear and oxidation.

Preparation of New WC-Co/TiC-Al2O3 Composite Materials with Mechanically Coated Particles.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2001
Mechanically coated particles may constitute a suitable starting point in the preparation of new composite materials. The properties of the sintered materials will depend on the degree of dispersion of the constituent particles throughout the formed material block.

Quantitative Characterization of Microstructure of WC-Co/TiC-Al2O3 Composite Materials with Relate to Mechanical Properties.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2003
The microstructure of WC-Co/TiC-Al2O3 sintered composites has been characterized quantitatively by means of image analysis. The areal fraction, the grain size distribution and the uniformity of spatial distribution expressed by the void size distribution of each component have been correlated with the mechanical properties of samples such as Vickers ...

Influence of TiC and Cr3C2 additions on the mechanical properties of a (W-Ti-Cr)C-Co sintered hardmetal

Journal of Materials Research and Technology, 2019
TiWCrC-Co alloys were manufactured by conventional powder metallurgy processes in a vacuum alumina furnace. The alloys were sintered at 1550 °C, and the chemical composition was changed in order to evaluate its influence on the mechanical properties of ...

New Design of Microstructure of WC-Co/TiC-Al2O3 Composite Materials by Mechanical Coating of Particles.

Journal of the Japan Society of Powder and Powder Metallurgy, 2002
In order to design a microstructure of a sintered composite material as uniform as possible, an experimental investigation was carried out by preparation of WC particles coated with Co, Al2O3, and TiC by high-speed rotational impact blending. The composite material was then fabricated by spark plasma sintering.
