“…Some of the advantages offered on those new Al-base components include: better wear resistance, strength to rupture [1][2][3][4] , modulus 5,6 , thermal stability 7 , among others. The aim of a composite material is to get a spectrum of properties that cannot be obtained by any of the constituent alone.…”

The present work deals with the study of some aluminum (Al) composites reinforced with metallized-graphite (MG) particles prepared by mechanical milling and powder metallurgy routes. Density, morphology evolution and mechanical performance of composites were investigated as a function of MG concentration and milling time. The as-milled powders were characterized by X-ray diffraction and optical/electron microscopy; meanwhile, the mechanical testing was carried out on cylindrical specimens prepared from powders by powder metallurgy. Evidence reveals that high-energy ball milling induce a homogeneous dispersion of graphite nanoparticles in the Al matrix; this is related to an enhancement of hardness and strength response of studied composites. The composite sample with 0.5% MG addition (in weight) reached an increase of 40% on hardness and 50% on strength (compared with pure Al sample); nevertheless an adverse effect was observed with longer milling and/or higher MG concentration.

“…Ultrasonic brazing is an elegant method to join Al-MMCs in air with the physical assistance. Due to the cavitation effect caused by the ultrasonic wave, not only the surface oxides are disrupted but also the wettability is enhanced [3][4][5][6][7][8][9]. However, higher ultrasonic wave energy may aggravate dissolution of the base metal, which leads to degradation of the substrate properties [10].…”

The semisolid brazing of SiCp/6063Al under an applied pressure using Zn-Al-Cu filler metal was investigated. The samples to be joined were heated from 380°C to 382°C, 386°C, 392°C, and 410°C under a constant pressure of 10 MPa, respectively. Effects of the temperature on microstructural evolution and deformation behavior of the filler metal, interfacial structure, and shear strength of the bonded joint were discussed, and the disruption behavior of the surface oxide film was studied. The results show that, after heating, the solid grains of the filler metal transform into a globular structure surrounded by liquid. The degree of sphericity and the liquid fraction tend to improve with increasing temperature. During the heating process, the deformation of the filler metal is first accomplished by plastic deformation of solid grains and then by intergrain sliding and liquid flow. The surface oxides are broken and stripped by a cocontribution of compressive and shear stress which is caused by depressing and sliding of solid grains along the composites. It is found that the heating of 380°C to 392°C under pressure is the optimum condition to disrupt the surface oxide films and obtain sound bonds. The mechanical test results show that the maximum shear strength of the bond joints is as high as 105 MPa, reaching 78% that of the parent materials.

“…Therefore, it is necessary to avoid the formation of Mg-Al IMCs by reducing the joining temperature lower than the Mg-Al intermetallic reaction point. Compared with those methods above, brazing or soldering has many advantages in joining Mg-Al, due to its variable solders and bonding temperature selection [12][13][14]. Wang et al [15] has designed a series of Sn-xZn solders for joining Mg/Al dissimilar metals.…”

A novel ultrasonic-assisted low-temperature soldering was developed to join AZ31B Mg alloy and 6061 Al alloy with a series of Sn-xZn solders. The average maximum shear strength of the joints reaches up to 87.5 MPa at soldering temperature of 300°C under ultrasonic assistance for only 5 s using Sn-20Zn solder. The fracture path propagates completely in the soldering seam. The results indicate that the microjet generated by ultrasonic pressure in liquid solder could strike and splinter the Mg 2 Sn intermetallic compounds into small pieces, which contributes to the enhancement of the joint strength. In addition, the primary Al(Zn) solid solution phase formed during cooling stage could also strengthen the joint due to the prevention of microcracks propagation.Acta Metallurgica Sinica (English Letters) (2019) 32:332-342 https://doi.org/10.1007/s40195-018-0749-x( 012 3456789(). ,-volV) (0123456789().,-volV)
