HHT-Project: Annual Report: Work Area 5: Material Development and Testing
Description
Automatic translation: Objective: For use for cover plates and fastening parts of the In the hot gas duct, materials with high creep strength at temperatures of up to around 1000 ° C are required. Under In terms of metals, this requirement is initially met by the blade materials for the helium turbine such as IN 713 LC or TZM, which are already being investigated elsewhere in the HHT project. With regard to manufacturing technology Problems and possible tendencies towards notch sensitivity With these highly heat-resistant materials, creep tests were carried out on forged materials based on nickel (Inconel 617, Hastelloy X, Nimonic 86, RGT 15). Additionally oxide dispersion strengthened alloys (ODS alloys) included, the potential of which must first be clarified on a random basis. For comparison with the above For blade materials, the investment casting alloy N 155 is being investigated. Identifying information about the test materials go from Table 1.
Abstract (German)
Zielsetzung: Zum Einsatz für Coverplates und Befestigungsteile des Heißgaskanals sind Werkstoffe mit hoher Zeitstandfestigkeit bei Temperaturen bis rd. 1000°C erforderlich. Unter den Metallen erfüllen diese Forderung zunächst die Schaufelwerkstoffe für die Heliumturbine wie IN 713 LC oder TZM, die an anderer Stelle im Projekt HHT bereits untersucht werden. Im Hinblick auf herstellungstechnologische Probleme und mögliche Tendenzen zur Kerbempfindlichkeit bei diesen hochwarmfesten Werkstoffen wurden Zeitstandversuche an Schmiedewerkstoffen auf Nickelbasis (Inconel 617, Hastelloy X, Nimonic 86, RGT 15) begonnen. Zusätzlich wurden oxiddispersionsverfestigte Legierungen (ODS-Legierungen) einbezogen, deren Potential zunächst stichprobenartig abzuklären ist. Zum Vergleich mit den oben genannten Schaufelwerkstoffen wird die Feingußlegierung N 155 untersucht. Kennzeichnende Angaben zu den Versuchswerkstoffen gehen aus Tabelle 1 hervor.
