| Popis: | In this work one presents the study realized to the compound materials: a) Zn77.0-Al22.0-Ag1.0 (wt. %) [Ternary Alloy], b) Zn77.0-Al22.0-Ag-1.0 (wt. %) [Compound Material 1] reinforced with 5 % of NaCl, and c) Al77.0-Zn22.0-Ag1.0 (wt. %)/Si [compound Material 2], the materials were incorporated by means of the alloyed mechanic in a time of grinding of 7 hours. The microstructural characterization was realized by means of: a) Diffraction of beams-X (DRX), b) Scanning Electronic Microscopy (SEM) and c) Microhardness Vickers (HV). The aim of this work was to study the effect of the microstructure and the hardness of a materials composed bases zinc and his comparison with a ternary alloy. Materials were obtained nanostructure by sizes of crystal in the ternary alloy of 94nm, and for the compound materials 1 and 2, 116 and 121 nm respectively. The values of hardness obtained for three systems have direct relation with the size of crystal. The image obtained to SEM at 7 hours of grinding suggests that the ternary alloy presents in the morphology bigger agglomerated particles and the compound material 2 particles small flakes. The results suggest that porous materials were obtained in three studied systems. Keywords: Mechanical alloy, Metallurgy of powders, Nanocomposite, Reinforcement with particles. |
