【 摘 要 】

The paper presents some results on analysis of some mechanical properties of AlMg10-SiCp composite materials, namely hardness and behaviour at static compression. Hardness values clearly separated the range of cellular composite materials from the porous ones, the compression tests data showing that with the increase of porosity the energy absorbed by the composite materials rises, the cellular composites requiring a higher mechanical deformation work that the porous ones. The increase of the silicon carbide percentage causes the increase of mechanical deformation work and of the absorbed energy, which can be explained by the stabilizing role of the respective particles on the composite material cells walls. The investigated samples were obtained using two methods: a method based on melt bubbling with a reactive gas (M1) and a method based on using various salts powders particles, soluble in suitable solvents (M2). We chose AlMg10 alloy for the material base and silicon carbide reinforcement particles introduced in varying amounts in the base mass (5%, 10% and 15% SiC). First method leads us to cellular composites and the second one to porous composites.
