BOYUT ETKİSİNİN MARTENSİT FAZ DÖNÜŞÜMÜNDEKİ ROLÜNÜN MOLEKÜLER DİNAMİK SİMÜLASYON YÖNTEMİ İLE İNCELENMESİ
Abstract
Şekil hafızalı alaşımların
nano-elektronik sistemlerde (NEMS) kullanılabilmesi için numune boyutunun faz
dönüşümü karakteristiği üzerine etkisinin belirlenmesi önemlidir. Bu çalışmada
Ni-at.%25Al şekil hafızalı alaşımının 5.76 nm den 20.1 nm ye kadar 6 farklı
boyutta modellenmiştir. Soğutma ve ısıtma işlemleri sonucunda meydana gelen
mastensit ve austenit faz dönüşümleri moleküler dinamik simülasyonları ile
incelenmiştir. Atomlararası fiziksel etkileşmelerin gömülü atom metodu (EAM)
ile temsil edildiği simülasyon çalışmaları LAMMPS yazılımı ile
gerçekleştirilmiştir. Model sistemlerde ortaya çıkan faz dönüşüm sıcaklıkları
termal analizler ile bulunmuştur. Model sistemlerin yapısal analizleri için
polihedral şablon eşleştirme (PTM) analizi kullanılmıştır. Faz dönüşümü
neticesinde ortaya çıkan martensit plakaların yönelimleri ve atomik dönmeler
rodrigues vektörleri ile elde edilmiştir. Sonuç olarak model boyutunun artması
ile martensit faz geçiş sıcaklığının üssel olarak azaldığı, austenit fazın
başlangıç değeri ve martensit plakaların yönelimlerinin boyuttan etkilendiği
gözlenmiştir.
