“…Javidani et al 73 found that solution heat treatment (SHT)deteriorated the microstructure of Al-Si alloys at 5250 ° C. The rate of solution heat treatment (SHT) process could control intermetallic Q and π-phases (Q-Al 5 Cu 2 Mg 8 Si 6 and π-Al 8 FeMg 3 Si 6 ) as thermodynamically stable or not. These intermetallic compounds dissolved or undissolved depends on Cu/Mg mass ratio variation above and below 2.6 and the percentage of Mg. Botelho et al 74 observed solidification parameters such as cooling rate and higher growth rate which influence AlNiBi alloy cellular and dendritic spacings. This Cellular morphology is close to the cooled casting surface as brittle intermetallic α(Al)+Al 3 Ni and Bi soft phase(β) droplets anchored α-Al observed along with inter-dendritic spacings.…”

Research on strengthening of Al alloys is rapidly increasing and producing defect free aluminum parts promising substantial movement in the view of manufacturing industries and automobiles. The intermetallic compounds, precipitates, hydrogen entrapment, and alloying elements play an important role in determining the strength of aluminum alloys. To acquire more comprehensive understanding of Al alloys and its mechanical and tribological performance as many research projects were developed. This review presents overview of research studies on the strengthening of Al with the incorporation of different alloying elements and how influence the mechanical, tribological performance &hydrogen entrapment which leads to cracks. Aluminum alloys mainly strengthened by solid solution strengthening, precipitation strengthening, grain /sub grain strengthening and dislocation strengthening. The nucleation and growth of these characteristics data is presented. Moreover, some research gap and challenges for these Al alloys are significantly considered within this review and to fill the gap proportionate research work recommended.
