“…Moreover, due to introducing hollow microspheres a smaller specific density and accordingly the weight of a bar are achieved, thus, allowing to more fully implementing MMC potentialities. The strength of the material saturated with metalized microspheres is thereat by 20% higher than the strength of a material saturated with conventional microspheres [18].…”

The scope of the use of aluminum-alloy-based metal-matrix composite materials has been expanding in recent years. However, the high cost of raw materials is a considerable deterrent to the widespread implementation of products made of such composites. Therefore, the ranges of the said materials commercial application are yet inadequate to their technical and operational capabilities. So, methods of making metal-matrix composite materials directly from a liquid melt are currently of interest. This paper presents the theoretical studies and the results of practical experiments for the production of metal-matrix composite material by the internal oxidation method. There are described the results of mechanical tests and the microstructure of specimens confirming theoretical assumptions in the oxidation of aluminum melt array. A comparative analysis is given for the cost of producing an alloy containing 30% of Al2O3 particles obtained by adding the Al2O3 powder and an alloy obtained by the internal oxidation of the aluminum melt. The studied technology provides for the formation of aluminum oxide directly in the aluminum melt, thus enabling to produce a composite material by a single-stage process and ensuring the process efficiency.

“…In paper [14] a technology was proposed for producing a low-density aluminum-based material by introducing into melt hollow ceramic microspheres, including those coated with chromium and chromium carbide to increase the melt adhesion to a microsphere. For these purposes the chemical gas-phase precipitation was used by the MOCVD method (Metal organic chemical vapor deposition [15 -20].…”

This paper deals with the study of capabilities for strengthening an aluminum alloy with hollow ceramic microspheres. The results of the microstructural analysis and the investigation of strength properties for the aluminum-silicon alloying system are described herein. For comparison Experiments have been carried out for comparison both with classical microspheres and with chromium- and chromium-carbide-coated microspheres to increase the melt adhesion to a microsphere
