Abstract

Al-Li alaşımları; düşük yoğunluk, yüksek elastisite modülü, mükemmel korozyon direnci, yüksek sertlik, yüksek yorulma çatlak büyüme direnci, düşük kırılma tokluğu ile havacılık endüstrisinin ilgi odağı haline gelmiştir. Alaşımların uçakların çeşitli yapısal parçalarında kullanımı devam ederken, ileride de kullanılması planlanan parçalar da mevcuttur. Her malzemede olduğu gibi bu alaşımlarda da çeşitli problemlerlerle karşılaşılmaktadır. Bu çalışmada Al‑Li alaşımlarının havacılık alanında kullanımı, karşılaşılan problemler ve çözüm önerileri incelenmiştir.

Keywords

Al Li alaşımları, Havacılık endüstrisi; Hafifletme; Kaynak kabiliyeti
