Dissertation: Production of Al/TiC metal matrix nanocomposites by means of hot press method and their characterization

  • Abstract: Compared to traditional metal matrix composites (MMC), in-situ metal matrix nanocomposites (MMNCs) own improved mechanical properties. MMNC is a multiphase material whose reinforcing phases are synthesized in the matrix by chemical reactions during fabrication. In the literature, the studies on the production process, mechanical and corrosive properties of these composites are relatively rare. In this study, Al-based composite reinforced with in-situ TiC nanoparticles was produced by conventional hot pressing. The microstructural, interfacial, mechanical properties and corrosive behavior of the produced composite were investigated. These tests indicated that the Al matrix reinforced with in-situ TiC nanoparticles improved the hardness, strength, and corrosion resistance. The equipment was used, are differential thermal analysis (DTA) to figure out the formation reactions during the sintering process, X-ray diffractometry (XRD) to obtain the phases and potentiostat system to examine the corrosive behaviors. In addition, scanning electron microscope (SEM) and transmission electron microscope (TEM) were to be used to examine the in-situ phase structures in the nanocomposites.

Master Thesis: Corrosion behaviors of Al-Si-Mg based SiC particle reinforced metal matrix composites

  • Abstract: In this study, corrosion behaviors were investigated of metal matrix composites (MMCs) based Al-7%Si-0.7%Mg reinforced with SiC particles 10, 20 vol.% respectively. Cyclic potentiodynamic polarization tests have been carried out to assess the effects reinforcement particle volume fraction, reactions product at the particle/matrix interface and voids at the interface on corrosion characteristics of both matrix alloy and composites in 3.5 wt.% NaCl aqueous solution, and then, the corrosion behavior of composites was determined by using Epit, Ecorr and icorr values obtained from polarization curves. In addition, the effect of aging heat treatment (T6) on the corrosion behavior of composites was investigated. The surface morphology of composites before and after the corrosion test was determined by optical microscopy and SEM, also, the XRD technique has been used in order to determine intermetallic phases that occurred at the matrix/SiC interface. At the end of the study, it has been found that pitting corrosion was the primary type of attack, and the corrosion resistance decreased with increased both SiC particle volume fraction and aging time in Al/SiC composites.
