Aging behavior of a 2024 Al alloy-SiCp composite

Investigation of friction and wear behaviors of 2024 Al and 2024 Al/SiCp composite at elevated temperatures

“…The mean hardness values of the composite and the unreinforced alloy were 185 and 136 HV, respectively. Further details of the synthesis and process parameters are mentioned elsewhere [13].…”

Effect of extrusion and particle volume fraction on the mechanical properties of SiC reinforced Al–Cu alloy composites

“…The peak-aged time of the unreinforced alloy and composites is both about 20 h. It should be noted that many matrix-particles interfaces exist in the composites and act as suitable sites for segregation of the solutes and stability of the precipitates. This leads to a lower concentration of the solutes in the matrix of the composite and causes a decrease in the degree of the solutes supersaturation, which causes a decrease in the chemical driving force for precipitation and therefore decelerates the aging kinetics [33]. However, the relatively long solution time enables the composites to have enough time to dissolve more precipitates, and thus, the effect of matrix-particles interfaces on the stability of precipitates has been greatly decreased [33].…”

Therefore, the peakaged times of the unreinforced alloy and the composites are very close to each other.…”

Influence Of Lubricants On Wear Resistance Of Aluminum Alloy Strips Series 2XXX

“…Research carried out in different friction conditions and using different lubricants have to search for the effects and relationships, enabling selection of the best lubricant to obtain more favorable conditions for conducting plastic forming processes in the aerospace, automotive and military applications where the 2024 alloy is used. In the literature there are, indeed, results in wear resistance of aluminum alloys 2XXX and composites based on these alloys [1][2][3][4] but they concern primarily the mechanisms and phenomena occurring at the interface between the material-tool without a focus on the leading role lubricants.…”
