Özet
In this study, the influence of 4, 5 and 6 at.% Ti addition on the mechanical properties of NiAl-Cr(Mo) eutectic alloy was investigated. The microstructure of the alloys were determined by using XRD, SEM, EDX analyses and mechanical properties were investigated by micro and macro hardness measurements and compression tests at room temperature and 1000 °C. The results showed that Ni2 AlTi Heusler phase precipitated in all Ti-added alloys and Ti addition inhibited eutectic cell formation by transforming lamellas Cr(Mo) phase into Cr(Mo) dendrites. In addition, hardness, room temperature and high temperature mechanical properties of NiAl-Cr(Mo) alloy improved significantly with the Ti addition. © 2015, National Institute of Optoelectronics.
