Abstract

Bu çalışmada geleneksel su verme ve derin kriyojenik
işlemlerin ve temperleme işleminin AISI H13 çeliğinin mikroyapısına, sertliğine
ve tokluk darbe enerjisine etkileri araştırılmıştır. Bu amaçla numunelere geleneksel
su verme ısıl işlemi ve -196 °C sıcaklıkta derin kriyojenik işlem
uygulanmıştır. Temperleme işleminin etkilerini belirleyebilmek için numunelere 560
°C sıcaklıkta 3 saat sureyle tek temperleme ve çift temperleme ısıl işlemleri
uygulanmıştır. Numunelerin mikroyapıları incelenmiş, sertlik ve darbe
enerjilerindeki değişim belirlenmiştir. Numunelerin mikroyapılarının martenzit,
kalıntı östenit ve karbür partiküllerinden oluştuğu gözlenmiştir.  Derin kriyojenik işlem ile kalıntı östenit
hacim oranın azaldığı ve ince ikincil karbür partiküllerinin oluştuğu
belirlenmiştir. Geleneksel su verme ve derin kriyojenik işlem uygulanan
numunelerde benzer sertlik ve darbe enerjisi değerleri elde edilmiştir. Temperleme ısıl işemine bağlı olarak sertlik değerlerinde ve
darbe enerjisi değerlerinde azalma gözlenmiştir.
