    Mechanical properties and corrosion resistance of cast NiAl alloys with the addition of Ti
    (2015) Hyjek, Paweł; Sulima, Iwona; Malczewski, Piotr
    Results of compression- and corrosion-resistance tests of NiAl alloys with 1.0 and 2.0 wt.% of titanium are described. The compression tests conducted at a wide range of temperatures, and the strain rate showed that an increase in titanium content causes increased brittleness at room temperature, while at higher temperatures, an increase of hardness and strength is observed. The analysis of electrochemical corrosion resistance showed that alloys containing Ti are characterized by considerable resistance to sulfuric acid VI, because the emerging titanium oxide prevents the active solubilization of the alloy. Besides, microstructure observations performed at various levels of deformation, which allowed us to identify the mechanisms responsible for fracture of the studied alloys.
