“…In consequence, the Al–12Ce–4Si–0.4Mg alloy with a higher CeAlSi 2 phase content exhibited greater tensile strength and strain hardening but less ductility than the Al–12Ce alloy, which was more prominent in the SC alloys. Other researchers have also reported on the impact of various precipitates on the strengthening of Al–Ce alloys [63–65].…”

In the present investigation, the microstructure and tensile properties of Al–12Ce, Al–12Ce–4Si, and Al–12Ce–4Si–0.4Mg alloys (wt-%), fabricated by suction-casting (SC) and gravity-casting (GC) were compared. The SC alloys exhibited finer grains and a higher number of precipitates than the GC alloys. Addition of Si and Mg in Al–12Ce alloy improved the hardness substantially. Incorporation of 4Si and 0.4Mg enhanced the yield and tensile stress but reduced ductility in the SC alloys. The SC Al-12Ce-4Si-0.4Mg alloy illustrated the best hardness and tensile strength. The fracture behaviour of the SC Al–12Ce alloy changed from quasi-cleavage to complete cleavage fracture following the addition of 4Si and 0.4Mg.

“…Among their other advantageous mechanical properties, bulk AlCu alloys are also known for their special aging behavior [34], which has been well studied and documented [35]. However, in the form of thin films, this special alloy is hardly discussed and only in cases with low Cu concentrations [36,37].…”

The novel, single-sample concept combinatorial method, the so-called micro-combinatory technique, has been shown to be suitable for the high-throughput and complex characterization of multicomponent thin films over an entire composition range. This review focuses on recent results regarding the characteristics of different binary and ternary films prepared by direct current (DC) and radiofrequency (RF) sputtering using the micro-combinatorial technique. In addition to the 3 mm diameter TEM grid used for microstructural analysis, by scaling up the substrate size to 10 × 25 mm, this novel approach has allowed for a comprehensive study of the properties of the materials as a function of their composition, which has been determined via transmission electron microscopy (TEM), scanning electron microscopy (SEM), Rutherford backscattering spectrometry (RBS), X-ray diffraction analysis (XRD), atomic force microscopy (AFM), spectroscopic ellipsometry, and nanoindentation studies. Thanks to the micro-combinatory technique, the characterization of multicomponent layers can be studied in greater detail and efficiency than before, which is beneficial for both research and practical applications. In addition to new scientific advances, we will briefly explore the potential for innovation with respect to this new high-throughput concept, including the creation of two- and three-component thin film databases.

“…Compaction pressure, sintering time and temperature, weight fraction of reinforcement are key factors on hardness values of Al composites which influences wear properties of the composite [2] In a recent paper, Rathod and Menghani, inspected the influence of precipitation hardening in aluminum based systems. They stated aging is a cost-efficient and simple method to achieve mechanical and wear improvements on Al based alloys [3]. Also, some previous studies indicate that ceramic and carbon reinforcements affect the precipitation hardening mechanism and result in different aging behavior [4], [5].…”

In this study, affect of aging on wear characteristics of the nano GNP reinforced Al6061 metal matrix composites. In this scope, the samples were produced by hot press at 500 ℃ temperature under 50 MPa pressure for 30 minutes. The wear characteristics of the composites were determined using the ball-on disc wear test method. The affect of aging on the friction coefficient and wear ratio were investigated. Graphene reinforcement significantly increased the friction coefficient between the stainless steel ball and specimen but aging process lowered the coefficient of friction to a better level. Also artificially aged specimens showed significant increase in hardness values. Key factors are affecting the mechanical performance of the Al based alloy is reinforcement and aging process.
