“…Sn introduction slows down the natural ageing process of 6000 Al alloys, thus helping in keeping the alloy stable during the transportation period from one place to another [5]. It was also observed that Zinc addition eliminates the negative effect of Sn addition in the properties of high magnesium content 6000 Al alloy [6]. Sn addition in 6000 alloys had been also shown as a potential accelerating artificial age hardening agent [7][8][9].…”

“…Alloying elements like Mg and Si in 6000 alloys reduce the dislocation motion through formation of hardening Mg 2 Si precipitates, thereby increasing the mechanical strength [4]. Sn in 6000 Al alloys is a potential trace element [5][6][7][8][9][10]. Sn introduction slows down the natural ageing process of 6000 Al alloys, thus helping in keeping the alloy stable during the transportation period from one place to another [5].…”

“…[10] also reported a positive effect in the tensile strength of 6000 alloy at lower Sn content of 0.03 wt.%. The previous studies of 6000 Al alloys with trace Sn are limited to the hardness [5][6][7][8][9][10][11] and tensile behaviour [6,[9][10]. It is worth mentioning that the studies on the impact behaviour and fractography of 6000 series aluminium alloys with trace Sn are limited.…”

The impact behaviour of 6061 alloy with trace amount of 0, 0.04, and 0.08 wt.% Sn was studied in the as-cast (AC), as-roll (AR) and peak-age roll (PAR) processing state. Additionally, the fracture mechanism was also studied in the AC and PAR state. The experimental investigation revealed that at all processing states, trace addition of Sn improves the impact strength of the 6061 alloy. Compared to the other processing states, the PAR condition contribute most to the impact strength. Fractography analyses showed that the fracture in the alloys occurred primarily by the crack propagation of Al(Fe, Mn)Si particles. The fractures in the AC alloys took place by mixed ductile and brittle mode by larger ductile dimples, cracks and cleavages, while in the PAR alloys was primarily by ductile mode by the smaller dimple fractures.

“…11,12 The effect of alloying Sn on the mechanical properties of the Al-Mg-Si alloy very much depends on the Mg/Si ratio and the ageing temperature. [13][14][15][16][17][18] At pre-aged (110 °C) and paint bake (165 °C) conditions, the negative effect of Sn (0.04 wt%) on the mechanical properties in high Mg-rich Al-Mg-Si alloy (Mg/Si = * 2) was observed by Glockel et al 14 However, the simultaneous addition of Zn (3 wt%) and Sn was found to prevent the negative effect and significantly improve the mechanical properties of the alloy. This was because Sn suppresses Mg-Si co-cluster formation, whereas Zn promotes Mg-Si co-cluster formation.…”

Microstructure and mechanical properties of the cast and wrought Al-Mg-Si alloy micro-alloyed with 0.04 wt% and 0.08 wt% Sn were investigated at various processing conditions, viz. as-cast, solutionised, homogenised, hot rolled and peak-aged. Additionally, fracture surfaces of the alloys were also examined in the as-cast, peak-aged cast and peak-aged rolled conditions. It was observed that 0.04 wt% Sn favours the formation of a lamella-like eutectic Al ? Mg 2 Si, whereas 0.08 wt% Sn favours the formation of plate/rod-like Mg 2 Si. The formation of the former deteriorated the hardness and tensile strength, but improves the ductility, whereas the formation of the later was found to contribute to the hardness, tensile strength as well as ductility of the Al-Mg-Si alloy. Homogenisation treatment had reduced the hardness of all the alloys to the lowest value due to the dissolution and spheroidisation of the intermetallic phases. However, hot rolling had significantly increased the hardness, tensile strength and ductility of the alloys. Thus, the increase in hardness, tensile strength and ductility were more prominent in the peakaged rolled alloys relative to the peak-aged cast alloys. At the studied processing stages, the hardness and tensile strength of Al-Mg-Si alloy were found to decrease with the addition of 0.04 wt% Sn and increase with the addition of 0.08 wt% Sn. However, the ductility increased with Sn addition, and the increment was more prominent when micro-alloyed with 0.04 wt% Sn. Improvement in ductility in 0.04 wt% Sn alloy could be attributed to the formation of script-like Al(Fe, Mn)Si phase, whereas in 0.08 wt% Sn alloy could be attributed to the formation of ductile Mg 2 (Si, Sn) phase. Furthermore, the fractography study had revealed that the fracture in the alloys was mainly developed by the cracking of Al(Fe, Mn)Si intermetallic particles. The fractures mode in the as-cast and peak-aged cast alloys was mainly by transgranular brittle with a cleavage fracture surface, whereas in the peak-aged rolled alloys was mainly by transgranular ductile with a dimpled fracture surface.

Cu-Sn-Zn alloys are excessively utilized in different manufacturing applications due to their unparalleled advantages, such as very its low resistivity, altitude business strength, and premium weld ability. Sn-4Zn alloy is concerning to the lead-liberation arrangement which is favourable in respect of the comparatively minimal fusion degree and minimal price. Nevertheless, Zn displays destitute oxidation and corrosion resistance which prevent welding employment. The present research studied the addition effect of Cu and CuO nanoparticles (NPS) on the transient creep properties of the Sn-4Zn alloy.Three compositions of Cu-Sn-Zn alloys were studied Sn-4Zn, Sn-4Zn-0.4CuO (NPS), and Sn-4Zn-1.5Cu (NPS). X-ray diffraction (XRD) and Scanning Electron Microscopy attached with Energy-dispersive X-ray spectroscopy (SEM-EDX) were used to investigate the microstructure of the prepared alloy samples. The results proved the addition of 0.4 CuO (NPS) to Sn-4Zn alloy increased the strength of the alloy by about 11%, while the addition of 1.5 Cu (NPS) increased the ductility of the alloy by about 14%. Additionally, the Creep property for Sn-4Zn; Sn-4Zn-0.4 CuO (NPS), and Sn-4Zn-1.5Cu (NPS)
