High temperature characteristics of Ni3Al alloys at various testing conditions

Popis výsledku v původním jazyce

Samples of Ni3Al based alloys with hypo-stoichiometric composition Ni24Al and Ni22Al were directionally solidified. Rate of directional solidification was between 50-70 mm/h. The samples were used for creep tests at 900 °C. Testing was performed under the load of 200 MPa. For selected samples smaller load was used. The samples were tested in an argon atmosphere. Due to the fact that materials of this type are used in demanding environments, the selected tests were performed in argon saturated with watervapour and in air. Creep characteristics for the analysis carried out in argon saturated with water vapour and in air were worse in comparison with results of tests carried out in an argon atmosphere. The Ni22Al alloy exhibits longer times to rupture than the alloy Ni24Al under the same testing conditions.
