In the production of high speed steel, the rolling a ects the micro-structure of the steel, which in turn in uences the mechanical properties. Speci cally, the distribution of carbide is essential, since cracks propagate within the carbide agglomerations. In current quality control, the properties of the steel are assessed manually by comparison with a standard chart, containing representative ...

A boron carbide coating was applied to diamond particles by heating the particles in a powder mixture consisting of H3BO3, B and Mg. The composition, bond state and coverage fraction of the boron carbide coating on the diamond particles were investigated. The boron carbide coating prefers to grow on the diamond (100) surface than on the diamond (111) surface. A stoichiometric B4C coating comple...

While empirical relationships between the mechanical properties of WC-Cocomposites and the carbide grain size and carbide volume fraction are qualitatively well-known, the influence of other microstructural features on the macroscopic properties hasbeen less clear. In this thesis, a comprehensive study of the effect of the interfacecharacter distribution (grain shape and misorie...

This review offers an overview on the latest advances in powder bed selective laser processing, known as sintering/melting, of calcium phosphate, silicon carbide, zirconia, alumina, and some their composites. A number published studies between 1991 August 2020 was collected, analyzed inclusive state art created for this review. The paper focuses process description, feedstock criteria parameter...

Near-isotropic pyrolytic carbon containing a small amount of co-deposited silicon carbide has been used for years as the materials from which prosthetic heart valves are fabricated [ 1 ]. Silicon carbide was introduced into this material to increase the hardness and thereby the wear resistance of the material. Silicon carbide, however, has poor thromboresistance relative to pyrolytic carbon, so...
