“…This reaction product Al 4 C 3 is very brittle, which degrades the composite material especially in humid environments. 14) Microscopically, the SEM images of the centers of the nugget cross-section, as shown in Fig. 7, suggest that the particle distribution in the matrix was almost uniform under all the processed conditions.…”

“…This suggests that no reaction occurred between the SiC and Al 2 O 3 powders or between the aluminum matrix and the powders during three FSP passes, which can be considered to be a merit of the FSP as a surfacing technique over other traditional fusion surfacing techniques such as laser beam and thermal spraying. 29) It was reported by many authors 14,21,30) that there were undesirable interfacial reactions between the matrix and the reinforcement during fabrication by liquid surfacing techniques. For example, Majumdar et al, 14) detected large Al-carbide plates at the SiC/Al of SiC particles introduced onto Al-substrate by laser injection.…”

“…[6][7][8][9] The widely used particles for reinforcing Al alloys are silicon carbide (SiC) and alumina (Al 2 O 3 ). [10][11][12][13][14][15] Besides their high hardness, they show low density and low cost comparing with other reinforcements. In the past two decades, the wear resistance of the aluminum alloys reinforced with SiC and Al 2 O 3 in many forms (particles, whiskers and fibers) and sizes has been described by a huge body of publications.…”

“…[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Most studies [6][7][8][9][10][11][12][13][14][15][16] proved that SiC was more effective than Al 2 O 3 in the improvement of wear resistance of the resultant aluminum composite due to its higher hardness. [6][7][8][9][10][11][12][13][14][15][16] On the other hand, some investigations [17][18][19][20] suggested that Al/Al 2 O 3 composites were more stable and inert, and had better corrosion and high temperature behavior than Al/SiC. [17][18][19][20] In this sense, it may become practical to use both SiC particles and Al 2 O 3 particles (hybrid) as reinforcements to gain both of their benefits for improving the composite properties.…”

Aluminum-base hybrid composites reinforced with mixtures of SiC and Al 2 O 3 particles 1.25 mm in average size have been fabricated on an A 1050-H24 aluminum plate by friction stir processing (FSP) and their wear resistance has been investigated as a function of the relative weight ratios of the particles. A mixture of SiC and Al 2 O 3 powders of different weight ratios was packed into a groove of 3 mm width and 1.5 mm depth cut on the aluminum plate, and covered with an aluminum sheet 2 mm thick. A FSP tool of square probe shape, rotated at a speed of 1500 rpm, was plunged into the plate through the cover sheet and the groove, and moved along the groove at a travelling speed of 1.66 mm/s. After the hybrid composite was fabricated on the Al plate, the homogeneity of the particles distribution inside the Al matrix has been evaluated from the macro/microstructure and hardness distribution. Moreover, the wear characteristics of the resulted hybrid composites were evaluated using a ball-on-disc wear tester at room temperatures at normal loads of 2 and 5 N. As a result, it was found that the reinforcement particles were distributed homogenously inside the nugget zone without any defects except some voids that appeared around the Al 2 O 3 particles. The average hardness decreased with increasing the relative content of Al 2 O 3 particles. Regarding the wear characteristics, the wear volume losses of the hybrid composites depended on the applied load and the relative ratio of SiC and Al 2 O 3 particles. The hybrid composite of 80% SiC þ 20% Al 2 O 3 showed superior wear resistance to 100% SiC and Al 2 O 3 or any other hybrid ratios at a normal load of 5 N.

Laser surface melting of hot pressed aluminum composite tile, consisting of 90 % aluminum and 10 % WC, is carried out. Temperature and stress fields developed in the laser-treated region are modeled and predicted using ABAQUS finite element code in line with the experimental conditions. The spiral motion of the laser beam is incorporated at the surface during the laser scanning. This arrangement provides self-annealing effect on the initially formed laser scanning tracks through heat conduction from the lately formed laser scanning tracks. Surface temperature predictions are validated through the thermocouple data. Morphological and metallurgical changes in the laser-treated layer are examined using optical and electron scanning microscopes. It is found that the cooling rates in the central region of the workpiece remain low because of the self-annealing effect of the lately formed laser scanning tracks. This, in turn, lowers von Mises stress levels in this region. Stress peaks are formed below the surface because of the high thermal strain formed in this region during the cooling cycle. The spiral scanning of the laser beam causes oscillating stress levels in the surface region of the laser-treated layer; in which case, its amplitude reduces with the progressing time. Laser-treated layer is free from cracks and crack networks, which is associated with the self-annealing effect of the lately formed laser scanning tracks.
