“…The solidification phenomena of the composite melt influences the distribution of Al 3 Zr particles in the matrix alloy. The molten matrix and Al 3 Zr particle have a density difference of 1.5 g/cm 3 which causes the in situ formed Al 3 Zr particles to suspend in the melt. The movement of the Al 3 Zr particles is retarded due to the wetting effect between Al 3 Zr particles and the melt which leads to the distribution of Al 3 Zr particles in the melt for a long time.…”

“…Aluminum matrix composites (AMCs) reinforced with various ceramic particles and intermetallic particles (Al 3 Ti, Al 3 Zr, Al 3 Ni, Al 3 Fe, etc.) have gained much attention in the last two decades because of their high elastic modulus and high specific strength both at ambient and elevated temperatures [1][2][3]. Al 3 Zr is very attractive compared to other intermetallic particles due to higher melting point (1850 K) and relatively low density (4.12 g/cm 3 ) [4].…”

Al 3 Zr is very attractive compared to other intermetallic particles due to higher melting point (1850 K) and relatively low density (4.12 g/cm 3 ) [4]. AMCs reinforced with intermetallic particles are fabricated using several methods including mechanical alloying, reactive sintering process, powder metallurgy and casting [5][6][7][8][9].…”

Friction stir processing (FSP) is a novel solid state technique to refine the microstructure of metallic materials. The objective of this work is to apply FSP to change the morphology and distribution of intermetallic particles and achieve property enhancement. AA6061/8wt. % Al 3 Zr composite was produced by the in situ reaction of molten aluminum and inorganic salt K 2 ZrF 6 . Optical and scanning electron micrographs revealed a uniform distribution of needle shape Al 3 Zr particles in the aluminum matrix. The Al 3 Zr particles were located in the inter granular spaces. A double pass FSP was carried out using a tool rotational speed of 1200 rpm, processing speed of 50 mm/min and axial force of 8 kN. A tool made of HCHCr steel; oil hardened to 62 HRC, having a hexagonal profile was used. The needle shape Al 3 Zr particles were fragmented and converted into a spherical shape subsequent to FSP which resulted an increase in the hardness of the composite.

The semisolid metal joining (SSMJ) process or thixojoining process has recently been developed based on the principles of SSM processing, which is a technology that involves the formation of metal alloys between solidus and liquidus temperatures. Thixojoining has many potential benefits, which has encouraged researchers to carry out feasibility studies on various materials that could be utilized in this process and which could transform the production of metal components. This paper reviews the findings in the literature to date in this evolving field, specifically, the experimental details, technology considerations for industrialization, and advantages and disadvantages of the various types of SSMJ methods that have been proposed. It also presents details of the range of materials that have been joined by using the SSMJ process. Furthermore, it highlights the huge potential of this process and future directions for further research.

“…The ultrasonic properties of the hexagonal closed packed structured Ag-Zn alloys were studied at room temperature [4]. The semi-solid stirring brazing process of SiCp/A356 composites and 2024 aluminum alloy was reported [5]. Especially, among a variety of inorganic particles, Fe-Ni alloy have been the subject of increasing interest due to their electrical, catalytic and magnetic properties and potential technological applications in catalysis, sensors, electromagnetic shielding and absorbing materials, and so forth [6].…”

Leaf-like Fe-Ni alloy have been synthesized via a facile hydrothermal approach without any soft and hard template. The structure of the leaf-like Fe-Ni alloy was characterized by Scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray energy-dispersive spectroscopy (EDX). The dendrite trunks lengths of the leaf-like Fe-Ni alloy were about 2.0μm-8.5 μm, and those of the branch trunk ranged from 850.0 nm to 4.0 μm. Furthermore, it was founded that the formation of leaflike Fe-Ni alloy strongly depended on the reaction temperature. Moreover, the magnetic and microwave absorption properties of products with various morphologies were also compared, and the result showed that the leaf-like Fe-Ni alloy had higher ferromagnetic and microwave absorption properties compared with spherical Fe-Ni alloy.
