Fabrication of Cu–SiC surface composite under ball collisions

Atomic-scale strengthening mechanism of dislocation-obstacle interaction in silicon carbide particle-reinforced copper matrix nanocomposites

“…Recent experiment [31] showed that the Cu + SiC nanocomposite is fabricated on a Cu plate at room temperature using ball collisions, and is in the same range as those of the reinforcing particles ( Fig. 1a).…”

Synthesis and characterization of titanium carbide particulate reinforced AA6082 aluminium alloy composites via friction stir processing

“…Research is being carried out across the globe to enhance the properties of AMCs using novel fabrication methods and reinforcements [1][2][3]. Conventionally AMCs are produced by liquid metallurgy routes such as stir casting [4], squeeze casting [5] and compo casting [6]. It is difficult to mix any kind of reinforcement to molten aluminium and keep it in suspension due to the poor wettability of both matrix and reinforcement [7].…”

Formation of nanolaminated amorphous/crystalline structure in the multicomponent system under severe plastic deformation

“…The components were introduced into the Cu surface one after the other in the order of Al, Zr, Ni and Co. The ball collisions after a series of 1 min pretreatments introduced the different particles from the grinding medium into the Cu surface at a depth of around 50 mm and produced a multicomponent surface composite layer [9]; thereafter, the as-fabricated layer was ball treated under the same experimental conditions for 1 h. The intermixing of the component on the nanoscale level was studied using Cs-corrected transmission electron microscopy (TEM) JEM-ARM200F. Focused ion beam instrument was used to prepare specimens for TEM.…”
