In the present study, a finite element model of microwave hybrid sintering along with experimental validation was developed. Multiphysics simulation at 2.45 GHz was carried out to understand the heat transfer behaviour and electric field distribution during the microwave hybrid sintering process. The proposed work presents an innovative and integrated approach for sintering aluminium utilizing microwave energy. Comparison with numerical simulation results and experimental data of temperature variation during microwave hybrid sintering was done. The maximum error predicted by the simulation model and experimental investigation for temperature variation in sintering was found to be within 10%. The X-ray diffraction analysis, relative density and microstructure analysis of the sintered aluminium was done to gain an insight into the material characteristics. The microhardness and nanoindentation tests were carried out to determine the hardness and elastic modulus. Good consolidation behaviour of aluminium with an achieved density of 0.9774, microhardness of 36Hv, nano-hardness as 0.5664 GPa and 57.301 GPa elastic modulus value has been observed. The study will develop a cogent link between the numerical model and experimental data for microwave hybrid sintering.

“…Various researchers have reported the relation between the nano-hardness and elastic modulus at small scale for different alloy and composite materials processed with different manufacturing paths. 16,21–24 However, as per the authors’ knowledge there is no literature available for the mechanical behavior of the Al/ZnO composite material at small scale. Therefore, the present study aims to assess the properties of the Al/ZnO composite with different amounts of the ZnO content in the functional characteristics of the Al.…”

The study focuses on the microstructural, phase transformation, and physical and mechanical aspects of aluminum/zinc oxide composite produced by a hybrid microwave sintering technique. In the present case, zinc oxide nanorods were synthesized through a cost-effective thermal decomposition method. The obtained zinc oxide nanorods’ length was in the range of 76–168 nm observed through high-resolution transmission electron microscopy images and crystallinity nature was confirmed by the bright spot in the selected area electron diffraction pattern. Two different wt% (i.e. 0.5 and 2) of zinc oxide nanorods were utilized for the fabrication of the composite material. The diffraction pattern of the milled powder and energy dispersive spectroscopy results shows effective diffusion of zinc oxide nanorods in the aluminum. The elemental mapping of milled powder illustrates the uniform distribution of the reinforcement over matrix material. The micro-hardness results exhibit a higher hardness of 27.78% with a small fraction of 2 wt%. The nano-indentation results confirm the improvement in the nano-hardness by 32.21% with 2 wt% of zinc oxide with a marginal decrease in elastic modulus by 4.92%.
