The two possible high-carbon phases in cast irons are graphite and Fe3C. Graphite is more stable and is the equilibrium structure. Graphite formation is promoted by slow cooling, high carbon and silicon contents, heavy or thick section sizes, inoculation practices, and the presence of sulfur, phosphorus, aluminum, magnesium, antimony, tin, copper, nickel, and cobalt.
Get PriceTurning experiments that were planned using the orthogonal array of L27were carried out using Tungsten carbide Al2O3 coated inserts varying the cutting speed, feed, and depth of cut. Cutting forces generated during turning at varying cutting …
Get PriceThis study investigates the mechanical properties of the wire + arc additively manufactured Inconel 625 thin wall. The first part of this study focused on the microstructural features of the material after time-based annealing. This second part discusses the tensile strength and microhardness of the material after the same annealing procedure (980 °C, hold time 30 min, 1 h, and 2 h). It is ...
Get PriceIt was observed that hardness had increasing effect for certain weight percentage of fly ash( up to 8 wt%) and above that level showed the negative effect on them. An increase of 63.6% in hardness and 107% in compressive strength was observed for the composite compared to pure aluminum. The increased ball milling time resulted in damage of CNT.

Get PriceTungsten carbide (WC) is an inorganic chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, other tools and instruments, and jewelry.
