Ayrıca optimum parametrelerin elde edildiği550 °C’de 2 saat temperlenen numunelerin dinamik deformasyon yaşlanmadavranışları araştırılmıştır. Yaşlandırma işleminde çekme deneyleri 25-700 °Csıcaklık aralığında ve 1x10-3 s-1 deformasyon oranındagerçekleştirilmiştir. Çekme sonucu kopan numunelerin kırık yüzeyleriincelenerek dinamik deformasyon yaşlanmasının kırılma davranışına etkisi tespitedilmiştir. Çekme sonuçları temperlenmiş numunelerin dinamik deformasyonyaşlanması ile tutarlı olarak 200 °C ve 300 °C&#039;de akma dayanımında ve maksimumçekme dayanımında bir artış olduğunu, ancak % uzama değerlerinin sabit kaldığını göstermiştir.AISI H10 sıcak iş takımçeliğinde dislokasyonlar ile arayer atomları (C veya N) veya yer alan atomları(Cr veya Mo) arasındaki etkileşim nedeniyle dinamik deformasyon yaşlanmasınınfarklı sıcaklıklarda meydana geldiği gözlenmiştir.</p></abstract>
