“…Due to the poor wettability between the Al6061 and the B 4 C particles, gaps may occur. 16,17 For this reason, despite the high deformation and high density, it was observed that there were traces of voids around some B 4 C particles. In a similar study, it was observed that gaps formed between the B 4 C particles and the matrix due to poor wettability.…”

“…It is also known that increasing cutting speeds in machining increase the cutting zone temperature. 17,18 As a result of the increase in the cutting zone temperature, the resistance of the material to cutting decreases and thus a decrease in cutting forces occurs. As the reinforcement ratio increased, the resistance to shear increased with the material strength.…”

In this study, composite materials with Al6061 alloy matrix and B4C particles reinforcement were produced by hot extrusion process. Fabricated composites were examined for the mechanical and machinability attributes. Al6061 alloy powders (<100 µm) and B4C particles (<10 µm) were mixed with the different weight fraction of B4C (3%, 6%, and 9% by weight) of and then cold pressed under 200 MPa pressure. The cold pressed powder metal block was extruded hot after preheating at 550°C for 1 h. Further, the composites were subjected to T6 aging heat treatment after hot extrusion. Microstructure, density, hardness, tensile strength, and wear properties were examined. The effects of cutting speed and cutting force on the machinability were also investigated. In addition, surface roughness and chips formation were examined. High density (99.6%) values were achieved with the extrusion process. With increasing B4C particles ratio, the hardness and tensile values were increased which was substantiated by the fracture morphology of the tensile specimens. It has been observed that tool smearing was high in the machining of the low-reinforced (3% B4C) composite. The highest cutting force was measured as 236 N at a feed rate of 0.27 mm/rev and a cutting speed of 250 m/min. It has also been observed that the average surface roughness decreased with increasing cutting speed and it increased with increasing feed rate.

“…Latterly, the SiC/Al and HEA/Al interfaces of hybridized composites were extensively investigated in respect to solution time and precipitation characteristics [25]. Metal matrix composites (MMCs), like Al-B4C, have several desirable properties, including high hardness, high strength, high resistance to chemicals, high neutron absorption capacity, and so on [26]. T6 treatment enhances the mechanical characteristics of the squeeze cast component by localizing the eutectic Si, refining the eutectic Si, homogenizing the composition for the produced component, and precipitating the Mg2Si phase in the α-Al matrix [27].…”

To segregate the Titanium (Ti) from the reinforcements of the molten scrap of Titanium/Aluminum (Ti/Al) composite, application of ultrasonic vibration is known to be one of the sound techniques. Various studies have been looked at the effect of ultrasonic vibration on the melting process, however not much have been investigated with respect to the solidification process. To fabricate Ti/Al composites in situ, ultrasonic vibration can be effectively used to compress the solidifying melt during the casting process. In this line, the present study focused to investigate the influence of ultrasonic vibration and squeeze pressure on solidification behavior of the α-Al matrix, characteristics of the matrix-reinforcements interface, and distribution of reinforcements. The experimental data indicated that when the amplitude was 60 μm, the Vickers hardness, yield strength, and tensile strength of composites increased by 8.6, 3.9, and 3.1 %, respectively, due to gravity casting. While the squeeze pressure was increased from 50 to 100 MPa, the mean grain size decreased from 90 to 60 μm during the ultrasonic aided squeeze casting (SC) process. However, as the squeeze pressure was raised, the microstructures became coarser and the mechanical characteristics weakened. Yield strength, and tensile strength were increased by 18.7% and 3.2%, respectively, when the squeeze pressure was 100 MPa.
