In this study, the influence of 4, 5 and 6 at.% Ti addition on the mechanical properties of NiAl-Cr(Mo) eutectic alloy was in-vestigated. 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 Ni2AlTi Heusler phase precipitated in all Ti-added alloys and Ti addition inhibited eutectic cell for-mation 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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
