AB  - Phase transition from ZnTiO3 to Zn2TiO4 represents second order phase transition from perovskite (zinc metatitanate) with a hexagonal ilmenite structure (R¯3) to inverse spinel (zinc orthotitanate) cubic structure (Fd¯3m) stable from room temperature to its melting (liquid) was identified during sintering of ZnTiO3 nanopowder. Kinetic of the phase transition has been observed as dimensional changes using dilatometric device thermo-mechanical analyzer TMA SETARAM model SETSYS Evolution and as thermal changes with SETARAM SETSYS Evolution TGA-DTA/DSC device. Two forms of specimens were employed nanopowder and polycrystalline sintered bulk specimen. It was found that sintering process and relaxation of the nanodimensional powder particles stress phenomena strongly influence kinetic of the phase transition. Dilatometric results known from previous investigations are now compared with differential thermal analysis results.

AB  - Nanocomposites are multiphase materials in which at least one of the structural compounds has a size below 100 nm. The subject of this work is creation of a dispersion-strengthened nanocomposite (DSC) with copper matrix. There are many dispersions that are possible to be used in DSC with copper matrix, such as Al2O3, Y3O2, TiO2, and WC. In this work we used Al2O3 due to the possibility of making even dispersion in the material and its economical availability. Such composites exhibit thermal stability of their mechanical properties up to 900 °C for at least 1 hour exposure, which opens new possibilities for use of such materials in high-temperature, high-strength applications. Materials created by our team exhibited good mechanical properties, namely hardness, which was up to 136 HB; however, it has to be noted that amount of dispersion particles had a direct effect on the hardness of the composite. Properties of the DSC´s are also dependent on the method of its preparation and compactization. Composites in this work were prepared by powder metallurgy method and sintered by spark plasma sintering, which allowed these composites to reach 99% density. Furthermore, DSCs were tested for their thermal stability, and their properties were evaluated and compared even with precipitation-strengthened copper-chrome material in order to show potential of possible usage of DSCs in spot welding applications, which require high strength, hardness, and electric conductivity.
