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.

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 ...
