Fe(1-x) – Al(x) ALAŞIM SİSTEMİNİN İKİNCİ DERECE ELASTİK SABİTLERİNİN GENELLEŞTİRİLMİŞ MORSE POTANSİYEL FONKSİYONU İLE HESAPLANMASI

Fe(1- x) – Al(x) alaşım sisteminin (x = 0.25 ve x = 0.30) ikinci dereceden elastik sabitleri Genelleştirilmiş Morse Potansiyel Fonksiyonu (G.M.F), potansiyel parametresi (m) ve kristal örgü sabitine (a1) bağlı olarak ayrı ayrı hesaplandı. Kristalin kararlılık sınırında (a0 = a1) elastik sabitlerin deneysel değerlere, m = 2 de, çok yakın olduğu görüldü. Kullanılan potansiyel fonksiyonun bcc yapıdaki alaşım kristaller için de uygulanabilirliği başarıyla test edildi.
