“…Aluminum alloys have a wide range of use, especially in the automotive and aerospace, electronics, machinery, and manufacturing industries due to their high strength compared to their weight, high mechanical properties such as low density, high corrosion resistance, and easy machinability. [1][2][3][4] However, the mechanical properties of many aluminum alloys such as tensile strength, hardness and wear resistance are lower than these mechanical properties of other materials commonly used in the industry. 5 Therefore, superior mechanical properties can be obtained by adding reinforcement material to the aluminum matrix.…”

Aluminum-based metal matrix composites are extensively used in applications in many industrial fields, especially in the aviation and automotive industry. The usage rate is increasing day by day. Therefore, it is very important to improve the mechanical properties of the composite structure. For this purpose, in this study, 3, 5, and 7 wt.% tungsten carbide (WC) reinforced aluminum matrix composite material was produced by stir casting method. The mechanical properties (tensile strength, hardness, wear) of the produced composite materials and their effect on machinability were investigated. The machinability process was performed in constant cutting speed, constant cutting depth, three different feed rates (0.05, 0.1, and 0.2 mm·rev−1), and dry environmental conditions. Wear tests were performed on dry sliding conditions, under 25 N load, covering different distances (150, 300, 450, and 600 m). In addition, the microstructure of the composite samples was analyzed using optical microscopy and scanning electron microscope. The phases in the composite material were determined using the X-ray diffraction technique. As a result of the experiments, with the addition of WC particles, the mechanical properties of the materials such as tensile strength, hardness, and wear resistance have increased and the machinability capability has decreased.

Yapılan bu çalışmada indüksiyonla sıcak presleme ve toz metalürjisi yöntemleri ile Al6061 matrisli Si3N4 (ağırlıkça %1-12) ve grafen (ağırlıkça %0,15-0,45) takviyeli kompozitler üretilmiştir. Üretilen kompozit malzemelerin yoğunluğu, sertliği, basma dayanımı, aşınma direnci, mikroyapısı ve faz yapısı sırasıyla incelenmiştir. Yapılan testler sonucunda en yoğun mikroyapı, en iyi mekanik ve tribolojik özellikler Al6061-%9Si3N4-%0.15grafen kompozit yapıda elde edilmiştir. Yürütülen ısıl işlem çalışmaları neticesinde ise; sinterleme sonrası indüksiyonla sıcak preslenmiş numunelerin mekanik ve tribolojik özelliklerinin yalnızca sinterlenmiş kompozitlere kıyasla ~%37’ye varan oranlarda iyileştiği tespit edilmiştir.

“…Due to its good weldability, high wear resistance, high elasticity modulus (70 GPa), low density (2.7 g/cm 3 ), good machinability, high thermal (230 W/mK), and electrical conductivity (63 MS/m), it is frequently utilized for a matrix element. [11][12][13] Besides, aluminum and its alloys are used in aviation, electronics, manufacturing, and automotive sectors, especially car bodies, car power trains, engine blocks, chassis, and suspension. 14,15 The reinforcing element is used in aluminum matrix composites (AMCs) to meet the requirements and enhance the material's properties.…”

This work intends to fabricate Al6061 alloy and Al6061-graphene composites via powder metallurgy and induction hot pressing techniques. This study also investigates the effect of graphene content (0.15, 0.30, and 0.45 wt.%), heat-treatment process (sintering, hot-pressing process), and applied load (5 and 10 N) on the compressive strength, hardness, density, mass loss, friction coefficient, wear rate, and microstructure. Tribological test results showed that minimum mass loss (0.0011 g), wear rate (8.5 × 10−8 mm3/(Nm)), and friction coefficient (0.23) were obtained at sintered and hot-pressed Al6061–0.15 wt.%graphene composite for a 5 N load. Hardness and compressive strength increased from 95 HV, 253 MPa (Al6061 alloy) to 151 HV, 395 MPa (Al6061–0.15 wt.%graphene) with sintering and induction hot pressing process, respectively. Compared to Al6061 alloy, the wear rate and compressive strength of Al6061–0.15 wt.%graphene improved by 30% and 33% for sintered and hot-pressed specimens, respectively. It has been determined that the tribological and mechanical properties of sintered and hot-pressed specimens are ∼15% better than those of only sintered samples. As a result of the paper, it was concluded that the addition of uniformly dispersed graphene and the induction hot-pressing process enhanced the mechanical and tribological behavior of aluminum-based composites.
