“…Regarding results obtained by Veeresh Kumar et al [19], Al6061-SiC composite produced using liquid metallurgy had higher wear resistance than produced F 2 and F 5 composite in this work. It could be due to higher hardness compared to F 2 and F 5 .…”

“…Table 1 lists the variation of 0.2% yield strength and ultimate strength of the composites with different SiC fractions. Regarding results obtained by Veeresh Kumar et al [19], Al6061-SiC composite produced using stir casting had lower mechanical properties than F 2 and F 5 produced in the present work. Against the present work, due to severe interaction between molten metal and reinforcement particles, the production of composite with higher SiC fraction (more than 6 wt%) using stir casting was impossible.…”

The objective of present work is to apply the friction stir processing (FSP) to fabricate functionally graded SiC particulate reinforced Al6061 composite and investigate the effect of SiC particle mass fraction distribution on the mechanical properties and wear behavior of Al6061/SiC composite. Regarding the obtained results in this work, with increasing SiC mass fraction, elongation decreased, but hardness enhanced. However, the optimized functionally graded composite with the highest tensile strength and wear resistance was achieved for composite with 10 wt% surface SiC. Also, the results showed that wear resistance and tensile strength decreased for composite with 13 wt% surface SiC, due to reinforcement particle clustering depending on high SiC mass fraction.

“…Among these alloys, especially the 2XXX, 6XXX, 7XXX Al alloys are preferred for their ageing properties. There are many recent studies that used 7XXX Al alloys as matrix material, which have the highest resistance among all Al alloys [1,[7][8][9]. In these studies, various carbides and oxides (such as SiC, Al 2 O 3 B 4 C, TiC, AlN, TiN, Al 4 C 3 ) have been used as reinforcement phase [10][11][12][13].…”

In this study, the effects of B4C amount on hardness and wear behaviours of 7075 Al-B4C composites produced by powder metallurgy method were investigated. Within the scope of work, different amount of B4C (3, 6, 9%) added into gas atomized 7075 Al powders. The powders were mixed in Turbula with 67 rpm for 45 min. Then the composite powders were pre-shaped by cold pressing under 600 MPa pressure. Pre-shaped samples were sintered in atmosphere controlled furnace at 580• C for 4 h. Scanning electron microscope, X-ray diffraction examinations and hardness measurements were carried out after standard metallographic processes. Wear tests were performed in a pin on type wear apparatus under 30 N with 1 m s −1 sliding speed, at six different sliding distances (500-3000 m). Results show that the hardness was increased with increasing of amount of B4C. At the end of wear tests the lowest weight loss were found to 9% B4C containing composites. In addition, it is determined that the weight loss increased with increasing sliding distance.

“…Al matrix composites are used in a number of fields including primarily automotive and space industry due to having low density, high toughness, and high corrosion resistance [1][2][3]. Aluminum composites are produced with addition of SiC, Al 2 O 3 , TiB 2 , B 4 C ceramic particles into Al alloys as reinforcement element have profoundly high strengths and wear resistances [4][5][6].…”

In this study, the effects of sintering time on hardness and wear behaviour were investigated of carbon nanotubes reinforced aluminium matrix composites. 1% multi wall carbon nanotubes (90% purity with 9.5 nm in diameter, 1.5 µm in length) and gas atomized 7075 Al alloy powders were mechanical milled for 120 min in a planetary ball mill. Mechanical milled aluminium composite powders were cold pressed under 520 MPa. Pre-shaped samples were sintered in atmosphere controlled furnace at 580• C for three different sintering times (1, 2, and 3 h). As a result of study, it was observed that the hardness values of composites were decreased with increasing sintering time and the weight loss was decreased. It was determined from worn surface SEM images that adhesive wear mechanisms were dominant.
