## 3 Results and Summary  
### Results  
Table 1 summarizes the metal matrix composites fabricated from the 5 xxx series of aluminium magnesium alloys using only marine grades reinforced with various reinforcements using the FSP process. The literature study reveals that SiC particles are the most frequent type of reinforcement that has been employed to develop composites.  
\begin{table}
\begin{tabular}{c c c c} \hline
**Reference** & **Base Material** & **Reinforcement** & **Outcome** \\ \hline
[35] & AA5052 & SiC & The results showed a 55\% increase in hardness value and a 9.7 times greater wear resistance than the AA5052 base material. \\ \hline
[37] & AI5052 & SiC & Hardness, yield strength, and UTS improved by 140, 60, and 75\%, respectively. \\ \hline
[39] & AA5052 & TiO\({}_{2}\) & At tool rotational speed and traverse speed of 1000 RPM and 65 mm/min, respectively, the maximum hardness and tensile strength values (78 \(\pm\) 1 Hv and 193.1 \(\pm\) 3 Mpa) were achieved. The grain boundaries of the cast AA5052 were found to have micro-voids. The specimen’s tensile test revealed the ductile fracture. There were no defects discovered in the FSPed zone. \\ \hline
[58] & AA5052-H32 & TiO\({}_{2}\), MgO and Al\({}_{3}\)Ti & Particles of Al\({}_{3}\)Ti and MgO (50 nm) were detected. The composite showed 90\% HAGBs and a grain size of 2 mm. At higher test temperatures, the composite’s deformation activation energy was discovered to be 456 kJ/mol. \\ \hline
[59] & AA5052-H32 & TiO\({}_{2}\) & The processing zone contains particles of Al\({}_{3}\)Ti and MgO. Pre-treatment decreased strain hardening and strain rate sensitivity. Annealed and wrought FSPed samples had microhardness of 87.9 \(\pm\) 2 and 82.4 \(\pm\) 1.6 Hv, respectively. \\ \hline
[60] & AA5052-H32 & TiO\({}_{2}\) & In a 2-mm fine-grained matrix, nanoscale Al\({}_{3}\)Ti, and MgO phases may be found. At high TiO\({}_{2}\) content (3.5 vol\(\%\)) and 6 FSP passes, a greater yield strength of 158 Mpa, an ultimate tensile strength of 252 Mpa, and an elastic modulus of 85 Gpa were recorded. With six FSP passes, the endurance limit of 154 and 148 Mpa was recorded at 2 and 3.5\% of the TiO\({}_{2}\) volume percent. \\ \hline
[61] & AA 5052 & GNPs & AMMCs’ improved mechanical characteristics \\ \hline
[62] & 5052 & ZrO\({}_{2}\) & The coefficient of friction (COF) was reduced with an increase in rotational speed during FSP of the ZrO\({}_{2}\) reinforced sample, increasing the wear resistance of aluminium alloy 5052 to 36.8\%. \\ \hline
[63] & AI 5052 & SiO\({}_{2}\) & SiO\({}_{2}\) homogenous dispersion was accomplished. \\ \hline
[40] & AA 5083 & SiC & A well-distributed, 50–200-lm thick AA5083/SiC surface composite layer with an excellent bonding matrix was created. The surface composite AA5083/27 vol\(\%\) SiC has a microhardness of almost twice as much as the AA5083 base material. \\ \hline
[42] & AA5083 & Cu & The best powder dispersion was reportedly obtained with a four FSP-pass count. \\ \hline
[46] & AA5083 & B\({}_{4}\)C & In the one-pass method, there were some visible reductions in the yield and ultimate tensile strength values of surface composites when compared to the non-reinforced samples. Despite this, it was shown that the surface composite microhardness was greater than that of the non-reinforced samples, and their wear rate was also lower. \\ \hline
[51] & AI 5083 & MWCNT & Tensile strength and hardness both increased by 38 and 18\%, respectively. \\ \hline \end{tabular}
