| Popis: | Versuchsdurchfuhrung unter Argonatmosphare bei 800, 900 und 1000 °C – mechanische Kennwerte bei Raumtemperatur in Abhangigkeit von Pruftemperatur und Auslagerzeit – licht- und elektronenoptische Untersuchung des Mikrogefuges – Zuordnung mechanischer Kennwerte und Mikrogefuge. Effects of Aging in Inert Gas at 800 to 1000 °C on the Mechanical Properties of X 10 NiCrAlTi32 20 Type Alloys Specimens of three casts of a X 10 NiCrAlTi32 20 type alloy with different carbon contents (0,04, 0,08 and 0,33 wt%) were annealed at 800, 900 and 1000°C between 6 and 900 h. Tensile- and notched bar impact-tests were performed at room temperature to characterize the changes of mechanical properties due to the heat treatments. The structural changes were recorded by optical metallography, scanning electron microscopy and transmission electron microscopy. The formation of fine dispersed M23C6-precipitates leads to hardening effects, which are lost by coarsening with longer annealing time or higher temperatures, where an embrittlement occurs. Only the low carbon version exhibits a dominant precipitation of Ti(C, N), especially at 1000°C, which maintains its ductility. |
