Abstract

This study investigates the affects of cryogenic treatment on the hardness, wear resistance, and microstructure changes of 1.2436 steel. In the study, shallow at −80 °C for 6 hours and deep cryogenic treatment at −180 °C for 6 hours were applied on quenched steel samples. In addition, the steel pieces were exposed to tempering at 300 °C for 2 hours at different stages. In the microstructure images, it was seen that the cryogenic treatment provided a more homogeneous carbide distribution in 1.2436 steel. The cryogenic treatment also substantially affected the wear resistance and hardness of 1.2436 steel. Deep cryogenic treatment provided higher hardness and wear resistance than shallow cryogenic treatment. The paramount hardness was acquired in the sample in which the tempering heat treatment was carried out between quenching and cryogenic treatment, and the paramount wear resistance was acquired in the piece in which the tempering heat treatment was performed after quenching and cryogenic treatment.

Özet

Bu çalışma, kriyojenik işlemin 1.2436 çeliğinin sertlik, aşınma direnci ve mikro yapı değişiklikleri üzerindeki etkilerini araştırmaktadır. Çalışmada su verilmiş çelik numunelere -80 °C'de 6 saat sığ ve -180 °C'de 6 saat derin kriyojenik işlem uygulanmıştır. Ayrıca çelik parçalar farklı aşamalarda 300 °C'de 2 saat süreyle temperleme işlemine tabi tutulmuştur. Mikroyapı görüntülerinde kriyojenik işlemin 1.2436 çelikte daha homojen bir karbür dağılımı sağladığı görülmüştür. Kriyojenik işlem aynı zamanda 1.2436 çeliğin aşınma direncini ve sertliğini de önemli ölçüde etkilemiştir. Derin kriyojenik işlem, sığ kriyojenik işleme göre daha yüksek sertlik ve aşınma direnci sağlamıştır. En yüksek sertlik, su verme ile kriyojenik işlem arasında temperleme ısıl işleminin uygulandığı numunede, en yüksek aşınma direnci ise su verme ve kriyojenik işlemden sonra temperleme ısıl işleminin uygulandığı numunede elde edilmiştir.
