Bu çalışmada Cu-23.10Al-2.50Be (% at.) şekil hafızalı alaşım (ŞHA) numuneleri farklı sürelerde Co-60 gama radyasyon kaynağı ile ışınlanmıştır. Gama radyasyon kaynağı ile ışınlanmış Cu-23.10Al-2.50Be şekil hafızalı alaşım numunelerinin ışınlama süresinin dönüşüm sıcaklıkları, termodinamik parametreler ve yapısal değişimler üzerindeki etkisi incelenmiştir. Işınlama süresine bağlı olarak, alaşım numunelerinin dönüşüm sıcaklıklarını ve termodinamik parametrelerini belirlemek için diferansiyel taramalı kalorimetrisi (DSC), yapısal değişimlerini belirlemek için, oda sıcaklığında X-ışını kırınım (XRD) ölçümleri ile incelenmiştir. Artan ışınlama süresi ile alaşım numunelerinin kristalit boyutunda meydana gelen değişimler belirlenmiştir

Anahtar Kelimeler

CuAlBe, şekil hafızalı alaşım, ışınlama süresi, kristalit boyutu
