“…However, since copper can diffuse easily to the interstices between TiC particles at a low concentration which leads to higher densification, so the resultant values of porosities are found to be very less in the fabricated composites. 33,34 Figure 5 also indicates that the increase in TiC content into matrix element increases the porosity of the prepared samples.…”

The present study has investigated the role of the addition of TiC nanoparticles on the microstructural, mechanical, physical, and metallurgical properties of the Cu-TiC nanocomposites. A Powder metallurgy route was used to fabricate the samples. Cold compaction of powders was done at 480 MPa which was followed by sintering at 950°C. Wt.% of TiC was varied from 0% to 20%. A Pin-On-Disc tribometer was used to carry out the wear and friction tests. SEM and EDS techniques were used to explicate the morphology and microstructures of worn surfaces and to comprehend the underlying wear mechanism. The fabricated samples were investigated against the applied normal load (10, 20, and 30 N), sliding speed (0.5, 1.0, and 1.5 m/s), and sliding distance (900, 1800, and 2700 m). The results revealed that the Hardness and tensile strength were improved by 88.76% and 37.26% respectively due to the addition of TiC and were maximum for Cu-20%TiC while the relative density shows the reverse trend. Further, it was found that wear resistance and coefficient of friction were improved by 87.18% and 51.85% respectively as a function of nano-TiC content. The presence of oxide layers and mechanically mixed layers are detected from worn surface analysis which modulates the tribological behavior of the contact.

“…Titanium alloys are used in a number of other industrial applications, including emission control, flue gas desulfurization, purified terepthalic acid (PTA) plants for polyester processing, pressure vessels, heat exchangers, and hydrometallurgical autoclaves. Each grade is customized to particular working conditions, with an emphasis on strength for various stresses, alloy quality for various corrosive agents, and ductility for various fabrication requirements [ 1 , 2 , 3 , 4 , 5 ]. Ti-6Al-4V (6% aluminum and 4% vanadium) is a titanium-based alloy that is widely used because of its high fatigue resistance and good corrosion resistance capacity.…”

Ti-6Al-4V is an alloy that has a high strength-to-weight ratio. It is known as an alpha-beta titanium alloy with excellent corrosion resistance. This alloy has a wide range of applications, e.g., in the aerospace and biomedical industries. Examples of alpha stabilizers are aluminum, oxygen, nitrogen, and carbon, which are added to titanium. Examples of beta stabilizers are titanium–iron, titanium–chromium, and titanium–manganese. Despite the exceptional properties, the processing of this titanium alloy is challenging when using conventional methods as it is quite a hard and tough material. Nonconventional methods are required to create intricate and complex geometries, which are difficult with the traditional methods. The present study focused on machining Ti-6Al-4V using wire electrical discharge machining (WEDM) and conducting numerous experiments to establish the machining parameters. The optimal setting of the machining parameters was predicted using a multiresponse optimization technique. Experiments were planned using the response surface methodology (RSM) technique and analysis of variance (ANOVA) was used to determine the significance and contribution of the input parameters to changes in the output characteristics (cutting speed and surface roughness). The cutting speed obtained during the processing of the annealed titanium alloy using WEDM was quite large as compared to the cutting speed obtained in the case of processing the pure, quenched, and hardened titanium alloys using WEDM. The maximum cutting speed obtained while processing the annealed titanium alloy was 1.75 mm/min.

“…23 The use of PM provides several advantages including finer and fully isotropic microstructure with homogenous distribution, [24][25][26] inexpensive mass production, 27,28 low defects due to porosity, 25 high material, and low energy utilization. 24 For example, Somani et al 29 fabricated different Cu-SiC MMC compositions using PM that resulted in an increase of hardness and tensile strength by 48% and 24% respectively by adding 20% of SiC. Moreover, experiments indicated that SiC reinforcement enhances the wear resistance capacity and reduces the coefficient of friction in the Cu-SiC composite.…”

Metal foams have drawn an increasing interest especially in applications where weight and energy absorption are critical. Despite the extensive studies available on their characterization and enhanced fabrication techniques, limited work was found on the possibility of producing a porous composite foam. The objective of this article is to investigate two new synthesis techniques for manufacturing metal matrix composite foam that is, powder metallurgy and melt infiltration. Both techniques are studied using Sodium Chloride (NaCl) as a space holder in an aluminum-based metal matrix and graphene nanoparticles as reinforcements. The effect of the quantity added of both the space holder and graphene is studied using designed experiments. Although powder metallurgy provided lower baseline hardness, experimentation results suggest the superiority of the process over melt infiltration in terms of porosity and hardness. Results suggest that baseline aluminum hardness can be increased by up to 21.5% using powder metallurgy and 15% using melt infiltration. In terms of porosity, powder metallurgy porosity increased baseline more than ten folds while melt infiltration only doubled the baseline porosity. Moreover, it is easier to control the macroscopic shape, density, and distribution of the pores using powder metallurgy. It is also easier to disperse the reinforcement homogenously. Results will support several industries such as military, automotive, medical, and aerospace in developing this innovative material with superior properties and coping with their need for advanced applications.
