Physical and chemical nature of cemented carbides
TL;DR: In this article, the physical and chemical aspects of transition metal carbides and iron-group metals are reviewed with emphasis on the materials science point of view focusing on those compositions which have gained technical interest.

Effect of carbide grain size on microstructure and sliding wear behavior of HVOF-sprayed WC–12% Co coatings
TL;DR: In this paper, the effect of carbide grain size on the wear behavior of WC-Co coatings was examined using dry sliding friction and wear tests using sintered alumina as the mating material.

Abrasion resistance of nanostructured and conventional cemented carbides
K. Jia,Traugott E. Fischer +1 more
TL;DR: In this article, the authors compared the abrasion resistance of nanostructured WCCo composites, synthesized by a novel spray conversion method, compared with that of conventional materials.
Journal ArticleDOI
Perspectives on the source, segregation and transport of granitoid magmas
TL;DR: In this paper, a collection of three largely independent and necessarily incomplete perspectives on the origin and evolution of granitoids is presented, and the authors suggest that the most compelling evidence for diapirism appears to be the lack of tectonic transport, whereas results of physical modelling yield contradictory results.
Journal ArticleDOI
Effect of Carbide Grain Size on the Sliding and Abrasive Wear Behavior of Thermally Sprayed WC-Co Coatings
TL;DR: In this paper, the carbide size and cobalt content of thermally sprayed tungsten carbide/cobalt coatings (WC-Co) can influence their microstructure, fracture strength, friction response and abrasion resistance.

Röntgenanalyse der Systeme Wolfram-Kohlenstoff und Molybdän-Kohlenstoff
Arne Westgren,Gösta Phragmén +1 more
TL;DR: In this article, a rontgenanalyse der Systeme WC and MoC is gefuhrt, e.g., 30 Atomprozent Kohlenstoff tritt in den beiden Systemen eine Phase der Struktur hexagonaler dichtester Kugelpackung auf, die wahrscheinlich eine feste Losung von Kohlen stoff in Wolfram oder Molybdan darstellt.

X‐Ray Stress Analysis of WC‐Co Cermets: II, Temperature Stresses*
TL;DR: In this paper, the effect of cobalt content on the temperature stress in WC-Co cermets was measured using both the "one-exposure" and "two-exposed" X-ray diffraction techniques.
