“…Parallel to the rapidly developing technology, expectations of the qualification of materials are also increasing. Over the several past decade's grain refinement has been mostly applied for enhancing the microstructural and mechanical properties of aluminum alloys through physical and chemical methods such as severe plastic deformation, mechanical alloying, conventional thermomechanical processing, and adding grain refiners [1][2][3][4][5]. Ultrasonic vibration (20 kHz-1 GHz frequencies) application is a relatively new method compared to the other methods used to improve the mechanical properties of materials.…”

The purpose of this study is examining the effects of ultrasonic melt treatment on microstructure and mechanical properties of the AlSi10Mg alloy. In this study, ultrasonic melt treatment with different frequencies and duration was applied to AlSi10Mg molten alloy. Also, T6 heat treatment was applied to samples which were obtained by ultrasonic melt treatment (UST) with different application parameters to investigate the combination of T6 heat treatment and UST effect on the microstructure and mechanical properties. The microstructure of cast samples was characterized by optical and scanning electron microscopy. Also, hardness and tensile tests were carried out. The results indicate that primary α-Al phases are transformed from coarse dendrites to smaller dendrites by the ultrasonic melt treatment. Besides, secondary dendrite arm spacing of the alloy decreased and mechanical properties such as hardness and tensile strength increased. UST reduces the secondary dendrite arm spacing (SDAS) of the aluminum alloy to 50 %. Additionally, increasing treatment time contributes to hardness up to 12 % and tensile strength up to 50 %.

The present transmission lines of populous cities will have to be changed with an ability to work at higher temperatures without any weight and cross section changes. Innovative thermal-resistant alloy conductors (T-ACSR) operate in the range of about 150200• C instead of 75 • C which is the standard ACSR type conductor service temperature. In this study, the manufacturing procedure of Al-Zr alloy wire, used as high-temperature conductor wires, have been introduced. The Al-Zr alloy has been cast in a permanent mold than being extruded to a diameter of 10 mm at 400• C. After that the extruded rods have been cold drawn to a diameter of 3.02 mm. Elongation and tensile strength values of the cold drawn wire have been achieved by tensile test at elevated temperatures. Also, microstructural analysis and dispersion hardening procedure have been investigated. The results show that tensile strength and thermal-resistant property are improved by the addition of Zr.

“…The minor Cu addition to the A356 alloy transforms the a-Al coarse dendritic structure into the equiaxed structure as elongated grain size reduced wear rate. Feyzullahog˘lu et al 88 assessed mechanical properties of Al-Si and Al-Pb alloys by heat treatment and forging effect. Normally in the heat treatment process, grain growth hardness was decreased then followed by forging means strain-induced which control the grain growth.…”

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.
