The increase in demand and introduction of stringent emission regulations resulted in the need to develop and implement innovative technologies towards improving the emission and performance characteristics of compression ignition engines. A hybrid metal matrix composite piston (HMMC) of Al7075 reinforced with 6% of 100 ?m Silicon Carbide (SiC) and 4% of 100 ?m Aluminium oxide (Al2O3) was fabricated. The HMMC piston was mounted on a compression ignition (CI) four stroke single-cylinder constant speed engine and the test was carried out with eddy current dynamometer attached with computerized data acquisition system. This paper is focused on the study of performance of Al7075-SiC-Alumina composite piston for compression ignition engine application. Experimental investigations were performed at injection pressure of 200 and 220 bar on both standard piston and HMMC piston and analysed the performance, combustion and emission behaviour of CI engine. From the results it was found that the HMMC piston exhibits an improved efficiency and thereby improving the lifetime of the engine. Though a little compromise in performance and emissions has been accepted, the implementation of HMMC pistons will reduce the carbon foot print of running an internal combustion engine.

“…The extensive involvement of friction, wear and lubrication in the variety of engineering applications makes tribology an important field for the overall developments in the industrial and economic fronts(Haq and Anand, 2018b; Kerni et al , 2018, 2019). According to Stachowiak (Stachowiak, 2017), “during the industrial revolution, it became clear that without advancements in tribology the technological progress would be limited.” Derived from the Greek word “tribos” the word “Tribology,” deals with the science of friction, wear and lubrication.…”

Purpose The involvement of wear, friction and lubrication in engineering systems and industrial applications makes it imperative to study the various aspects of tribology in relation with advanced technologies and concepts. The concept of Industry 4.0 and its implementation further faces a lot of barriers, particularly in developing economies. Real-time and reliable data is an important enabler for the implementation of the concept of Industry 4.0. For availability of reliable and real-time data about various tribological systems is crucial in applying the various concepts of Industry 4.0. This paper aims to attempt to highlight the role of sensors related to friction, wear and lubrication in implementing Industry 4.0 in various tribology-related industries and equipment. Design/methodology/approach A through literature review has been done to study the interrelationships between the availability of tribology-related data and implementation of Industry 4.0 are also discussed. Relevant and recent research papers from prominent databases have been included. A detailed overview about the various types of sensors used in generating tribological data is also presented. Some studies related to the application of machine learning and artificial intelligence (AI) are also included in the paper. A discussion on fault diagnosis and cyber physical systems in connection with tribology has also been included. Findings Industry 4.0 and tribology are interconnected through various means and the various pillars of Industry 4.0 such as big data, AI can effectively be implemented in various tribological systems. Data is an important parameter in the effective application of concepts of Industry 4.0 in the tribological environment. Sensors have a vital role to play in the implementation of Industry 4.0 in tribological systems. Determining the machine health, carrying out maintenance in off-shore and remote mechanical systems is possible by applying online-real-time data acquisition. Originality/value The paper tries to relate the pillars of Industry 4.0 with various aspects of tribology. The paper is a first of its kind wherein the interdisciplinary field of tribology has been linked with Industry 4.0. The paper also highlights the role of sensors in generating tribological data related to the critical parameters, such as wear rate, coefficient of friction, surface roughness which is critical in implementing the various pillars of Industry 4.0.

“…With a view to pursuing the best cast alloy design, the quality index (QI) is a single parameter proposed in the literature to evaluate the tensile strength, considering the influence of chemical composition, microstructure, and heat treatment. [24] QI is given by Equation (1) [25][26][27] QI ¼ σ U þ d log ðδÞ (1) where d is a material constant and QI is dependent on the ultimate tensile strength (σ U ) and elongation to fracture (δ). QI has already been used to compare the effects of grain refinement and modification in an Al-12 wt% Si alloy.…”

Morphology of Intermetallics Tailoring Tensile Properties and Quality Index of a Eutectic Al–Si–Ni Alloy

The Al-Si-Ni alloy system is a source of multicomponent piston alloys, which combine good castability and wear resistance of Al-Si alloys with great thermal stability and corrosion resistance of Al-Ni alloys. [1-3] The inherent high piston temperature during engine functioning is one of the limiting factors for the application of Al-Si-based alloys. [4] On the other hand, alloys containing Al-Ni-based intermetallic compounds (IMCs) are mainly used for high-temperature structural products, which also demand wear resistance, such as aircraft engines, turbine vanes, and guide vanes of industrial steam turbines. [5,6] The formation of Ni-rich IMCs occurs even for low Ni concentrations, [7] as Ni is almost insoluble in aluminum, with a solubility of about 0.05 wt% at 640 ºC and less than 0.005 wt% at 450 ºC. [8] Thus, the addition of Ni to Al─Si alloys can potentially improve their wear resistance at elevated temperatures. Once the second phases are responsible for these characteristics, the modification of the microstructure, regarding its refinement, usually improves the properties and extends the lifetime of the component. Apart from the formation of different IMCs, the addition of new alloying elements can promote modification of other phases, mainly on Si. Kaya and Aker [9] studied ternary Al-12.6 wt% Si-2 wt% X alloys, where X was Cu, Co, Ni, Sb, or Bi. They verified that the addition of Co promotes a better distribution of Si flakes (i.e., smallest interflake spacings) and, consequently, highest hardness and tensile strength are achieved. Although the addition of Cu induced the least efficient refinement effect, the Al-12.6 wt% Si-2 wt% Cu alloy showed the second highest tensile properties. This occurred probably due to the formation of a supersaturated solid solution and hard Al 2 Cu particles. As Al 2 Cu and Al 9 Co 2 have similar hardness (588 [10] and 568 HV, [11] respectively), and Co is restricted to the formation of Al 9 Co 2 , the refinement of Si seems to have a major effect on mechanical properties. The aforementioned alloying elements are not modifiers of the eutectic Si morphology, but they just decrease the interflake spacing. Sr is a strong modifier, which is capable of transforming the acicular Si in welldistributed fibers with only a few hundred parts per million. In an Al-10 wt% Si alloy, 240 ppm of Sr has the same effect as 520 ppm of Ti-B grain refiner in terms of tensile properties. [12] Another Si modifier, Sc, also decreases the secondary dendritic arm spacing and refines the grain size; however, it requires an amount 20 times greater than that of Sr to improve the mechanical properties at the same level. [13] In secondary aluminum, Mn, [14,15] Cr, [16,17] Ni, [18,19] and other alloying elements are added to suppress the precipitation of harmful β-AlFeSi, aiming at the formation of α-AlFeSi, which has a Chinese-script morphology. Even though modification is, in general, desirable, excessive addition can lead to overmodification. Riestra et al. [20] observed in Al-11 wt% Mg 2 Si alloys, in ...
