“…After the test, crack surfaces are introduced for microstructural concentrates on utilizing SEM to comprehend the break system. Compression tests were carried out on 20 mm diameter and 60 mm length as built specimens as per ASTM https://www.indjst.org/ E9 (16) standard. On each orientations three samples were tested for tensile and compression, average reading was tabulated in the graphs using error bars.…”

Objective: To evaluate the tensile and compression behaviour of Al-Si10-Mg alloy developed by selective laser melting (SLM) process. Method: Al-Mg10-Si alloy developed by SLM process along XY (45°) and Z (90°) orientations. These prepared samples were subjected to microstructural characterization by SEM and EDS. Mechanical properties like tensile and compression behaviours were evaluated according to ASTM standards. Findings: Microstructural studies revealed the effect of grains on the mechanical behaviour of Al-Mg10-Si alloy built in XY (45°) and Z (90°) orientations. EDS analysis confirmed the presence of Mg and Si elements in the Al matrix. Tensile strength of Al-Mg10-Si alloy built in XY (45°) orientation is 428.6 MPa against 408.3 MPa in Z (90°) orientations developed samples. Further, compression strength of samples developed in XY (45°) orientation is more than that of developed in Z (90°) orientations. Novelty:In the current study Al-Mg10-Si alloy samples were produced by selective laser meting method in XY (45°) and Z (90°) orientations. Very minimal investigations were carried out on Al-Mg10-Si alloy specimens built in XY (45°) orientation.

“…This hard molecule keeps away from the plastic progression of Al grid and subsequently upgrades the load carrying limit of Al2030 matrix. Pankaj et al (13) investigated the effect of boron carbide content on the properties of A356 alloy; the addition of B 4 C particles improved the tensile strength of A356 alloy.…”

“…The abatement in flexibility is a result of the accompanying reasons (I) void nucleation by expanding expansion level of support. The particular clarification for this distinction might be that B 4 C molecule acts like a pressure concentrator ii) the strong interfacial strength with support and network is incredibly high, prompting more prominent support load, along these lines cracking at lower strains (13,14) .…”

Objective: To synthesize and assess the mechanical behaviour of 12 wt. % of 80 to 90 micron sized B 4 C reinforced Al2030 alloy metal composites. Method: Al2030 alloy with 12 wt. % of B 4 C reinforced composites were developed by liquid melt stir cast method. These prepared composites were subjected to microstructural characterization by SEM, EDS and XRD. Mechanical properties like hardness, tensile and flexural strength were evaluated according to ASTM standards. Findings: Scanning electron micrograph of Al2030 alloy with 12 wt. % of B 4 C composites revealed the thorough distribution of boron carbide particles in the Al2030 matrix. EDS and X-ray diffractometer patterns confirmed the presence of boron carbide particles in the Al2030 alloy matrix. The addition of 12 wt. % of B 4 C particles enhanced the hardness by 74.8%, ultimate strength by 59.2%, yield strength by 64.8% and flexural strength by 44.2% with slight decrease in ductility. Novelty: Al2030 alloy is an aerospace grade aluminium alloy widely used for industrial applications. Advanced metal composites developed with the incorporation of 80 to 90 micron sized B 4 C particles in Al2030 alloy helps in weight reduction of aerospace components.

“…Furthermore, there is an increasing environmental threat that engine blocks pose to the environment. Engine blocks are not biodegradable and the use of organic biodegradable materials as reinforcements in A356 alloy composite has not been exploited [5,[10][11][12]. So, to what extent has the disposed engine blocks (i.e.…”

In recent years, novel products from out–of–use A356 alloy engine components are increasingly produced for the automobile industries. Despite being a promising method the sand casting of these products reveals an inadequately understood cast geometry phenomenon for the process. At present, there is no technical solution to the optimisation of cast geometries for A356 alloy reconfigured into composites through organic matter reinforcements. This paper models and analyse sand casting process product geometries in a two–phase method. It utilises the response surface methodology with data on inputs and outputs to create the regression. Volume and density of the first casting process and the weight loss were evaluated for the various groupings of casting process variables, including length, weight, height, width of product for the first casting, weight, length, breadth of the product for the second casting, and the total weight of organic materials. The input and output associations were established in two models of regression analysis representing the central composite design, CCD. The influences of the cast geometrical variables on the evaluated responses were analysed. Furthermore, the predictive accuracy of the two regression models was evaluated. Results revealed that the applied CCD and the regression models reveals statistical adequacy and are competent to predict accurately.
