“…The tested specimens exhibit similar patterns that reveal the presence of Aluminium and Stainless steel metal. The sharp diffraction peaks correspond to the crystalline nature of Al1050 and SS304 layer [18][19][20][21][22][23][24] whereas diffused diffraction peaks correspond to the amorphous nature of the Adhesive layer [25]. The XRD test shows a sharp peak at an angle of 38 figure 1.…”

The utilization of the sandwich composite sheets for the specific industrial application depends upon its material properties. The present study investigates the mechanical and thermal properties of Al1050/SS304 sandwich composite sheets which could be used for the manufacturing of automobile sheet metal components such as a car body. The XRD (X-ray powder diffraction) and FTIR (Fouriertransform infrared spectroscopy) are performed to investigate the molecular structural arrangement and adhesive bonds whereas the composite wall test is performed to investigate the thermal conductivity by using different approaches. The experimental approach integrated with the analytical approach is utilized to validate the obtained thermal conductivity using a numerical approach. The thermal conductivity of 2.84 W mK −1 is obtained by using a numerical approach which is in good correlation with the experimental results.

“…The N is the number of reflections observed. The obtained texture coefficient TC(hkl) for the Al1050 sheet and SS304 sheet is 3.81(220) and 1.91 (102) [19][20][21][22][23][24][25]. The strain (ε) in the Al1050 and SS304 sheet utilised for the manufacturing of the Al1050/SS304 sandwich composite is determined by using equation…”

“…Lightweight materials such as aluminum alloys, of which the strength to weight ratio is superior to that of steel, have been widely applied on automotive parts to reduce their weight [1][2][3][4]. However, the surface roughness of aluminum alloy has a significant influence on the performance of mechanical parts as well as production cost [5].…”

The purpose of this study is to investigate the cutting performance of amorphous carbon (a-C) coatings and hydrogenated amorphous carbon (a-C:H) coatings on machining 2A50 aluminum alloy. First-principles molecular dynamics simulation was applied to investigate the effect of hydrogen on the interaction between coatings and workpiece. The cross-section topography and internal structure of a-C and a-C:H films were characterized by field emission scanning electron microscopy and Raman spectroscopy. The surface roughness of the deposited films and processed workpiece were measured using a white light interferometer. The results show that the a-C-coated tool had the highest service life of 121 m and the best workpiece surface quality (Sq parameter of 0.23 μm) while the workpiece surface roughness Sq parameter was 0.35 and 0.52 μm when machined by the a-C:H-coated and the uncoated tool, respectively. Meanwhile, the build-up edge was observed on the a-C:H-coated tool and a layer of aluminum alloy was observed to have adhered to the surface of the uncoated tool at its stable stage. An interface model that examined the interactions between H-terminated diamond (111)/Al(111) surfaces revealed that H atoms would move laterally with the action of cutting heat (549 K) and increase the interaction between a-C:H and Al surfaces; therefore, Al was prone to adhere to the a-C:H-coated tool surface. The a-C coating shows better performance on cutting aluminum alloy than the a-C:H coating.

“…Once microwaves are absorbed, metallic materials get heated uniformly at molecular level, irrespective of the material volume. Certain works have been reported regarding melting and casting of metallic materials through MHH [23][24][25][26][27][28]. Further, it has been reported that microwave processing results in enhanced mechanical properties of the processed material [29][30][31].…”

Material deterioration caused during service life led to the development of erosive/corrosive resistant materials. The present work focuses on characterization of an alloy, naval brass, developed by microwave hybrid heating method, which is a vital material used in ship building/ marine industry. Mechanism of melting of metals by microwave hybrid heating technique is presented in the article. Microstructural study reveals formation of alpha and beta phases, with negligible porosity. X-Ray Diffraction study reveals the presence of CuZn phase in the developed alloy. Further, tensile and microhardness characteristics of the cast alloy holds good with the properties that must be exhibited by the specified standard material.
