Carbide-Matrix Reactions in Wear Resistant Alloysot only good corrosion resistance, due to the nickel solid solution which often contains chromium, but also high abrasion resistance and a relatively low melting point. Aside from nickel and chromium, most nickel hard alloys contain boron and silicon, and often small amounts of additional carbon and

These methods, though simple and convenient, often do not produce adequate contrast for detailed microscopic observation and analysis. Other etching methods such as, ion sputter etching or simply ion-etching, are of a more recent origin. They are principally used in the pre

The objective of the conference was to review and advance the state of knowledge of the basic physical and chemical properties of hard materials and show how these properties influence performance in a variety of applications.

Progesterone

Hardness Measurements in the Evaluation of Hard Materialsare especially relevant to the hardest materials and which would benefit from further research. In particular, we shall be concerned with the implications of anisotropy for our understanding of the effects of varying normal load, temperature, and indentation creep.

Mechanical Behavior and Electron Microscopy Analysis of W2C study of plastic deformation of W.C at high temperatures (between 800° and 2200°C). In the present study, electron microscope observations (100 KV and 1 MeV) and results of mechanical deformation tests are associated so as to determine the process responsible for the plastic deformation of W.C.

Ion-Etching Techniques for Microstructural Characterization of Cemented Carbides and Ceramicsfeasibility of applying ion-etching methods for microstructural characterization of cemented carbides and ceramics is examined. Ion-etching is found to give improved contrast between binder phase grains in cemented carbides as well as reveal macroscopic heterogenieties in certain ceramics.

Carbide-Matrix Reactions in Wear Resistant Alloyslow melting point. Aside from nickel and chromium, most nickel hard alloys contain boron and silicon, and often small amounts of additional carbon and iron. Boron is very slightly soluble in nickel. The boride Ni.B forms a low melting eutectic at about 1.000°C with nickel or nickel solid solution.

Binder-Carbide Phase Interactions in Titanium Carbide Base Systemsresence of a Ni-rich liquid phase. Binder Ti and Mo levels were measured using this technique, which has a major advantage over phase separation analysis due to the ability to locate the analysis position with respect to the microstructural components.
