“…Therefore, nanostructured material can be produced by either creating new solid solution phase or forming a supersaturated solution. Besides, it has been reported that nanocomposite with grain size ranging from 5 to 50 nm [ 20 , 21 , 22 , 23 , 24 , 25 ] and dislocation densities around 1015–1016 mm −3 can be obtained by MA [ 26 ]. Moreover, a recently developed method combining both powder metallurgy (PM) and MA has produced very excellent results on the mechanical properties of various Cu-based composite systems [ 27 , 28 , 29 , 30 , 31 ].…”

In this study, an in situ nanostructured copper tungsten carbide composite was synthesized by mechanical alloying (MA) and the powder metallurgy route. The microstructure and phase changes of the composite were characterized by X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy. Tungsten carbide phases (WC and W2C) were only present after MA and combination of sintering. Higher energy associated with a longer milling time was beneficial for the formation of WC. Formation of W2C and WC resulted from internal refinement due to heavy plastic deformation in the composite. The solubility of the phases in the as-milled and sintered composite was described by the changes of the lattice parameter of Cu. Chemical analysis of the surface of a composite of W 4f and C 1s revealed that the increased defects introduced by MA affect the atomic binding of the W-C interaction.

“…Saji et al [11] reported that the supersaturated solute carbon atoms occupy the interstitial positions in the facecentered cubic (fcc) α-Cu solid solution, resulting in expansion of the lattice parameter of the α-Cu. High-energy ball milling increases the solid solubility limit and is used for alloying of low solubility or immiscible systems such as Cu-Cr, Cu-nb, and Cu-C alloys [13][14][15][16]. however, studies on the addition of carbon to Cu-Sn alloys with high tin contents are insufficient.…”

Microstructure and Hardness of cu-22sn-xc alloys fabricated by Powder MetallurgyCu-Sn alloys have been known as bronze since ancient times and widely used as electrode materials, ornaments, tableware and musical instruments. Cu-22Sn alloy fabrication by hot forging process is a Korean traditional forged high-tin bronze. The tin content is 22 percent, which is more than twice that of bronze ware traditionally used in China and the west. Copper and tin have a carbon solubility of several ppm at room temperature, making Cu-Sn-C alloys difficult to manufacture by conventional casting methods. research on the production of carbon-added copper alloys has used a manufacturing method that is different from the conventional casting method. in this study, Cu-22Sn-xC alloy was fabricated by mechanical alloying and spark plasma sintering. The carbon solubility was confirmed in Cu-Sn alloy through mechanical alloying. The lattice parameter increased from a0 to C2, and then decreased from C4. The microstructural characteristics of sintered alloys were determined using X-ray diffraction and microscopic analysis. as a result of comparing the hardness of Cu-22Sn alloys manufactured by conventional rolling, casting, and forging and Cu-22Sn-xC alloy by sintered powder metallugy, b0 sintered alloy was the highest at about 110.9 hrb.
