Noch nicht restlos geklärt war die Frage nach der Herstellungstechnik. Aufgrund von Materialzusammensetzung und früheren Untersuchungen war bekannt, dass die Scheibe in ihrer endgültigen Größe nicht einfach gegossen worden sein konnte. Metallografische Analysen zeigen nun, dass die Himmelsscheibe in einem aufwendigen Warmschmiedeprozess hergestellt wurde. Bis sie ihre endgültigen Ausmaße erreichte, waren ungefähr zehn Zyklen nötig, die jeweils ein Erhitzen bis auf ca. 700 °C, Ausschmieden und Glühen umfassten, um das Metallgefüge wieder zu entspannen.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":9911,"journal":{"name":"Chemie in Unserer Zeit","volume":"59 2","pages":"57"},"PeriodicalIF":0.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ciuz.202570201","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
