“…Spray forming is also suitable for those metal which have a poor affinity or bonding together like titanium and steel [51]. A number of research studies on the development of magnesium MMC using the spray forming method have examined the relationships between the spray processing parameters, the microstructure, and the mechanical properties of the composites [52][53] [54].…”

The magnesium is selected for the future implants material due to its excellent biocompatibility behavior. The biodegradable and biocompatible nature of Mg and its alloy make it prime choice for the development of bio-implants. The mechanical properties of Mg are similar to natural human bone therefore it can be used for temporary implantation for supporting a fracture bone. The rapid biodegradation of pure Mg before the healing time, raise the requirement to develop a metal matrix composites of Mg. The prominent technique of MMC fabrication is friction stir processing (FSP). The FSP is widely used for fabrication of surface composites and also used for grain structure refining and strengthening. The current article reviewed the various surface composites of Mg developed by FSP for alteration of biodegradation and mechanical properties. .

“…It is known that the high stiffness and strength per unit weight make sandwich type panels suitable for modern aircrafts and aerospace vehicles, boats and high rise buildings. 8 In foam based sandwich panel, additionally a core foam core is placed between two thin plates which make them strong and flexible. [9][10] Another simple panel can be understood as if only foam is used to support the load and there is no any extra support in it.…”

The sandwich panel exhibits higher stiffness than simple panels. The specific stiffness of sandwich panels depends on various factors like width, length, panel’s thickness, thickness of the face plate and core’s thickness of panels and type of materials used. Because of interaction effect between core and face plate, there is possibility of getting higher stiffness in multi-layered sandwich panels. In addition, incorporation of faceplate and core in the core structure varies the shear modulus and elastic modulus of core of the sandwich. However very limited research has been conducted on analytical modelling of multi-layered sandwich panels for their designing. In the present work analytical model has been developed to analyse the multilayer sandwich panels in terms of shear rigidity. flexural rigidity and deflection as a function of face plate thickness, core thickness, number of layers and beam width. Four types of specimens, those are single layer, double layer, triple layer and quadruple layer sandwich beam were prepared for this study. The deflection of the sandwich beam was measured by UTM (ultimate tensile machine). For core, Al- foam has been used and the theoretical values of elastic modulus and shear modulus were taken from the data available for cores of Al- foam synthesized at AMPRI, Bhopal. The deflection at 1000 N calculated theoretically for single layer and quadruple layer was 14.966 mm and 0.559 mm respectively. The practical calculation of deflection was 15.608 mm for single layer and 0.557 mm for quadruple layer. The practical and theoretical calculations were in well agreement. Further, it was understood that multi-layered sandwich panels are much more advantageous in terms of low deflection than single layer or double or triple sandwich panel.

“…Because of these excellent physical and mechanical properties, the foam has been used in numerous fields such as automotive, aerospace industries, railway, and structural applications for passenger saf In recent years, cenosphere domain because of its huge availability, spherical nature, excellent thermal insulation and attractive cell wall mechanical and wear properties, which make candidate for application as space holder to develop composite foam [7][8][9]. Several researchers have reported that the incorporation of cenosphere in the aluminium matrix effectively develops aluminium foam with reduced density, increased compressive strength and improved r properties [9][10][11][12][13]. The overall mechanical properties can be evaluated by conventional mechanical testing.…”

The present work aims at understanding the effect of process parameters on the porosity and forming route. A detailed investigation of the microporosity and nano have been undertaken through microcomputer tomography (µ respectively. The µ maximum of CF have been by nanoindentation analysis and compared with commercially pure (CP) aluminium. The sphericity results of the foam show that the pores are near spherical (with a sph diameter is below 50 µm, beyond which, the sphericity index decreases (0.175 to 0.4). The results of nanoindentation (for CP aluminium) to 673±54 MPa and energy absorption from 86±10 however; it decreases the elastic modulus from 58±3 (for CP
