    The microstructure analysis of powder-processed Ni-based superalloy

  • Original language description

    The aim of present work is to study the high temperature degradation of the powder-processed superalloy Ni-15Cr-18Co-4Al-3.5Ti-5Mo. This superalloy has been applied as material for grips of a creep machine. The material was exposed at 1100 °C for about 10 days at 10 MPa stress. During the creep test occurred unacceptable creep deformation of grips as well as severe surface oxidation with scales peeling off. Three types of the microstructure were observed in the studied alloy. It is shown that the microstructure degradation resulting from the revealed ?´ phase fcc Ni3(Al,Ti) particles preferentially created at the grain boundaries of the samples after performing creep tests affects mechanical properties of the alloy. Based on our investigation the material is not recommended to be used for grips of creep machine at above 1000 °C.
