“…The micron size reinforced metal matrix composites can achieve good strength; however, the ductility of the material reduces. The micron size particles have less surface area to volume ratio and act as micro-crack initiators in the matrix, which leads to a remarkable decrement in the ductility of the composites [3][4][5][6]. Many researchers proved that the ceramic nano-sized particle reinforced metal matrix composites attained good strength with similar ductility of the metal matrix [6][7][8].…”

The present study focused on the wear performance of AA6061/ SiCp (1, 1.5 and 2 wt. %) of nanocomposites at dry sliding condition. The nanocomposite specimens were fabricated through ultrasonic assisted stir casting technique. The wear experiments were conducted under normal atmospheric conditions using a pin-on-disc apparatus. Three different applied normal loads on nanocomposite pin (10 N, 15 N, and 20 N); at various sliding velocities of (1 m/s, 1.5 m/s, and 2 m/s); and at sliding distances of (1000 m, 2000 m, and 3000 m) were considered. The influences of applied normal load on nanocomposite pin, wt. % of SiCp reinforcement particles, sliding velocity, and sliding distance on both friction coefficient and wear loss were studied. The changes of wear loss and friction coefficient with varying applied normal loads, sliding velocities, and sliding distances were plotted. It was observed that the wear loss increased linearly with increasing sliding distance and sliding velocity. This was due to the increase of oxidation layer on the pin surface. The average friction coefficient at sliding velocity 1 m/s for 1 wt. % of SiCp, 1.5 wt. % of SiCp, and 2 wt. % of SiCp reinforced nanocomposites at sliding distance 3000 m, at 20 N normal loads was 0.29, 0.43, and 0.46, respectively. The average friction coefficient at 2 m/s sliding velocity for the same load and sliding distance was 0.26, 0.27, and 0.28, respectively. The increase of SiCp reinforcement in the matrix increased the friction coefficient due to its cubic crystal structure. The increase of sliding velocity and sliding distances reduced the friction coefficient. The worn surfaces of the samples were examined using SEM and EDX analyses. SEM micrograph analysis of the wear surfaces of the nanocomposites exhibited the abrasion wear and oxidative wear with severe plastic deformation. The shallower scratches, circular grooves, and deeper grooves were identified at different conditions on the worn surfaces.

“…Aluminum alloys are currently used in various sectors because of their higher quality characteristics like low specific gravity, corrosion resistance and recyclability [1][2][3]. Nowadays, their application is still expanding, mostly in the automobile and aerospace industries [4][5][6]. As shown in the study by Fortain and Gadrey [7], the main applications of aluminum products have been in transportation (27%), construction (20%), packaging (16%), electricity supply (10%), machinery and equipment (8%) and also in sectors relating to sustainable products (7%) where extraordinary growth reaching 60 million tons by 2020 has been predicted.…”

Innovative welding technology in joining aluminum alloys in the automobile, aviation, aerospace and marine industries would achieve weight reduction and high specific strength as well as increasing fuel efficiency and reducing environmental pollution. This study presents an appropriate welding filler to join similar AA6061 aluminum alloys using the tungsten inert gas (TIG) process. The TIG welding of AA6061 was butt joined with three different fillers: ER5356 (4.5-6% Mg), ER4043 (4.5-6% Si) and ER4047 (11-13% Si). The experiments were conducted in order to investigate the macrostructure and microstructure of the samples as well as the mechanical properties. The effect of preheating was also investigated. The effects of the different fillers used on the weld joints were analyzed by their visual appearance, microstructures, hardness and strength. It was found that welding by using filler ER5356 produced a finer grain size and the highest strength of 171.53 MPa compared to the weld joints using fillers ER4047 and ER4047 with values of 167.34 MPa and 168.03 MPa, respectively.

“…There is no doubt that the cutting efficiency gets improved if the cutting temperature is maintained at low levels. The effect of the cutting temperature is detrimental to the life of the tool and the workpiece surface quality.Literature contains a lot of reports on experimental studies that are based on experiments that have utilised various techniques meant for determining the cutting temperature and its distributions along the cutting edge of the tool [7][8][9][10][11][12][13]. Such studies have been successful in accurately predicting the cutting temperature, thanks to the new improvements and developments in instrumentation and data acquisition techniques.…”

The paper is concerned with the development of a data acquisition system for the measurement of temperature used for metal cutting. In this study, machining tests were performed and an analysis of the temperature and wear of the cutting tool is presented herein. In metal cutting operations, the wear of tools is generated largely due to the heat emitted from the cutting zone. Therefore, a coolant is often used to cool down the cutting area and protect the cutting tools. However, because of environmental concerns, engineers now try to avoid using cutting coolants and perform cutting operations in almost dry conditions. In this study, a mild-steel round bar was turned at various feed rates, depths of cut and cutting speeds. A data acquisition system was built to record the cutting temperature while turning the bar. From the study, it is evident that certain combinations of cutting parameters result in higher temperatures than those produced in other experiments. It was established that the depth of cut and cutting speed at their highest values (1 mm and 250 m/min, respectively) contribute largely to the high surface temperature, while the effect of feed rate is intangible. Increasing the cutting speed results in an increase in the cutting temperature. A similar result was observed when the depth of cut was increased. However, increases in feed rate did not significantly cause increases in cutting temperature. In addition, cutting inserts were examined under a scanning electron microscope (SEM) to quantify the tool wear in each experiment. A correlation between tool wear and temperature is clearly noticed. The study concluded that the combination of variations in cutting speed and depth of cut results in severe tool wear action on the tool's flank face as a result of the intensive heat generated.
