Abstract

This study investigates the effects of shallow cryogenic treatment on the microstructure, hardness and wear resistance of 1.2436 steel. For this purpose, quenched (QT) 1.2436 steel samples were subjected to shallow cryogenic treatment at -80 °C for 12 hours (SCT12) and 18 hours (SCT18). Hardness measurement and wear test were carried out on the samples and the samples were examined microstructurally. As a result of the study, it was observed that the cryogenic treatment provided a denser and homogeneous carbide distribution in the microstructure of 1.2436 steel. The amount of carbide in the microstructure increased by 18.80% with shallow cryogenic treatment for 18 hours. As a result of the hardness and wear tests, it was determined that the cryogenic treatment positively affected the hardness and wear resistance of 1.2436 steel. Compared to the quenched sample alone, the sample cryogenically treated for 18 hours exhibited 9.28% higher hardness and 34.37% less wear.

Özet

Bu çalışma, sığ kriyojenik işlemin 1.2436 çeliğin mikroyapısı, sertliği ve aşınma direnci üzerindeki etkilerini araştırmaktadır. Bu amaçla, su verilmiş (QT) 1.2436 çelik numunelere -80 °C'de 12 saat (SCT12) ve 18 saat (SCT18) için sığ kriyojenik işlem uygulanmıştır. Numuneler üzerinde sertlik ölçümü ve aşınma testi gerçekleştirilmiş ve numuneler mikroyapısal olarak incelenmiştir. Çalışma sonucunda kriyojenik işlemin 1.2436 çeliğin mikro yapısında daha yoğun ve homojen bir karbür dağılımı sağladığı gözlemlenmiştir. 18 saat süre sığ kriyojenik işlem ile mikroyapıdaki karbür miktarı yaklaşık %18,80 oranda artmıştır. Sertlik ve aşınma testleri sonucunda kriyojenik işlemin 1.2436 çeliğin sertliğini ve aşınma direncini olumlu yönde etkilediği tespit edilmiştir. Yalnızca su verilmiş numune ile karşılaştırıldığında, 18 saat boyunca kriyojenik işlem görmüş numune %9.64 daha yüksek sertlik ve %34.37 daha az aşınma sergilemiştir.
