“…Therefore, it is better to express the grain size in terms of aspect ratio. [ 4 ] The aspect ratio of Al‐grains increases with the increase in thickness reduction as shown in Figure 1b. This ratio is 1.6:2.2 (Figure 1b) for 40% thickness reduction.…”

“…The reduction in thickness is accompanied by an elongation of the Al‐grains in the rolling direction [ 4 ] as shown in Figures 1b–4b. In the preliminary stage of rolling, that is, about 40% reduction, movement of porous mass resulting in the removal of porosity.…”

“…Therefore, the spray formed sample must be densified further to obtain the desired properties. There are quite a lot of methods to densify the material such as rolling, [ 3,4 ] forging, extrusion [ 5 ] etc. However, rolling is the most proficient process because of having both normal and deviatoric stresses.…”

In the present work, the microstructural studies of spray deposited Al-6Si alloys with different lead content are conducted for 0% and 40% of rolling deformation. SEM and Optical micrographs are taken for different percentage of lead content. Fine equiaxed grain morphology is observed with a uniform distribution of Pb and Si phase in an Al-matrix and it is found from the microstructures that the size of Pb particles increased with the increase in Pb content. Grains are stretched out in the rolling direction after cold rolling. Pore size is found to decrease after 40% rolling reduction, however, it is increased with the increase in Pb content.

“…Accordingly, several works are being performed taking lead and graphite reinforcement to Al-Si alloys. [3][4][5][6][7][8][9][10][11] Commonly, it is observed that mixing of Pb and graphite have severe effect on the properties of Al-alloys such as, ductility, formability, and thermal conductivity. However, due to wide liquid immiscibility gap over different composition and over range of temperature selection with large density difference of Al and Pb, early techniques are not suitable for casting these alloys.…”

This article addresses the tribological characteristics and the influence of mechanical work on the porosity of spray formed Al–Si–Pb alloys. Al‐alloys are extensively utilized in industry due to their self‐lubricant qualities, particularly in the bearing company. In the case of immiscible alloys, the spray approach is the most convenient way to adopt since it allows for single‐step fabrication. The spray process has a high cooling rate, which affects the microstructure of alloys and results in equiaxed grain morphology. Spray deposition and several factors affecting to it are discussed here. This study examines the effect of secondary processes such as cold rolling, hot rolling, extrusion, and so on on porosity, hardness, tensile strength, and tribological behavior. A comprehensive knowledge of the principles of spray techniques and their respective influence on tribological properties are discussed in this perspective by comparing the available literatures, and a future scope for better development is emphasized.
