“…A barrier is created by the reinforced material particles to the plastic deformation (dislocation movement) done by the indenter during the hardness test resulting increment in the hardness of the AMMCs. 19 The output of microhardness test of all compositions is shown in Table 7. The improvement in hardness for SR-15 composite is 29%, 16%, and 6.4% when compared to LM 25 alloy, SR-5, and SR-10 composites, respectively.…”

The present study investigates the tribological behavior of aluminum and silicon (Si) alloy (LM25) based hybrid metal matrix composite (MMC). LM25 alloy is reinforced with three different percentages (5, 10, and 15 wt. %) in a 1:1 ratio of sillimanite and red mud particles utilizing the stir casting method. An analysis of the microstructure shows morphology of reinforcement particles throughout the alloy matrix. Pin-on-disk tests have been performed as per the Box-Behnken Design (BBD) technique to evaluate wear and friction characteristics. Further effect of reinforcement, sliding velocity, and applied load on wear and friction characteristics were analyzed and optimize as 13.48 wt. % reinforcement, 10 N load and 1.5 m/s sliding speed to get optimum properties. SEM analysis showed that the composite surface was more susceptible to wear under high loads since it had a higher degree of deformation.

“…They can be used to prepare reinforced parts such as fan blades and low-pressure turbine shafts, which are widely used in high-performance aero-engines [1,2]. However, the poor performance of fibres in the transverse direction makes the transverse strength of the composite less than one-third of that in the longitudinal direction; fan blades, low-pressure turbine shafts, and other reinforced parts of aero-engines are subject to significant transverse loads during practical operation [3,4]. For the parts of aero-engines, large transverse loads often exceed the transverse strength limits of the material, resulting in structural failure [5] of the component.…”

The transverse strength of long SiC fibre-reinforced metal matrix composites is superior to its longitudinal strength owing to interface factors. To accurately predict the transverse strength of long SiC fibre-reinforced metal matrix composites, a micro-mechanics representative volume element (RVE) model was developed; periodic boundary conditions were applied to the model to ensure its displacement and stress continuity. Taking into account the influence of the stress concentration coefficient of the matrix, the failure strength of long SiC fibre-reinforced metal matrix composites under transverse tensile loads and compressive loads were calculated, where the error between the calculation results of the model and the test results was found to be large. A novel calculation method based on the interfacial cohesion model is proposed herein, to improve the accuracy of the RVE model. It was found that the accuracy of the corrected model calculation has been improved through a comparison with the experimental values. The stress/strain relationship between interfaces of different strengths under tensile and compressive loads was analysed, the failure index of interface strength was extracted, and the relationship between the influence of interface strength on failure was determined.

“…The mechanical properties are improved up to 5 weight % of reinforcement. Incorporation of more than 5 % by weight of sillimanite reinforcement had no significant effect on the composite's mechanical properties [10]. The aluminium metal matrix composites reinforced with rutile and sillimanite mineral with LM27 aluminium-silicon alloy as matrix material are fabricated through stir casting method.…”

This paper investigates the mechanical and thermal characterization of hybrid metal matrix composites of sillimanite/red mud/LM25 aluminium alloy produced by stir casting process. The weight percentage of red mud and sillimanite are taken 5 %, 10 % and 15 % in the ratio of 1 : 1. Energy dispersive spectroscopy confirmed that both reinforcements are present in the base alloy. The aluminium‐metal matrix composites exhibit symmetrical distribution of red mud and sillimanite particles when observed through microscopic images, with minimal agglomeration. A detailed analysis is performed on the composites to determine the effects of sillimanite and red mud content on its tensile strength, thermal conductivity and hardness. Experimental results show that the accumulation of reinforcing material enhances the ultimate tensile strength and hardness at the expense of percentage elongation and thermal conductivity.
