Şekil
hafızalı alaşımlar genel olarak termal aktive ile istenilen görevleri yerine
getirmektedirler. Bu nedenden dolayı sıcak ortamlarda bulunmak veya bu termal döngülere
maruz kalmaları doğal ortamlarını oluşturmaktadır. Bu çalışmada oda
sıcaklığının üzerinde karakteristik dönüşüm sergileyen şekil hafızalı TiNi alaşımı
kullanılmıştır. TiNi alaşımına 200°C derece sıcaklığında farklı sürelerde yaşlandırma
işlemi uygulanarak yaşlandırma süresinin termal ve yapısal özellikleri nasıl
etkilediği araştırılmıştır.

Anahtar Kelimeler
