Titul/název v původním jazyce: Creep characteristics of Zr-doped Ni3Al based alloy
Popis výsledku v původním jazyce
Creep characteristics were determined in directionally solidified Ni3Al based alloy. Foundry alloy was alloyed by zirconium and its nominal composition was Ni-22Al-1Zr. Foundry alloy was prepared by method of vacuum induction casting, it was melted in acorundum crucible and cast into a graphite mould. The rods manufactured in this way were directionally solidified by Bridgman?s method in corundum tubes with a specific angle. Test specimens with length of 62 mm and body diameter of 3.5 mm were turned out from central parts. The specimens thus prepared were suitable for determination of basic high temperature characteristics. The following test parameters were chosen for uninterrupted creep tests ? testing temperature of 900°C and applied nominal load of 80 MPa. The determined creep characteristics differ significantly in dependence on conditions of directional solidification. Material structure before and after creep was investigated on cross sections; phase composition, micro-hardness
