Abstract

This work investigates the impact of tempering temperature on the mechanical properties quenched 1.2842 (O2) cold work tool steel depending on the volume fraction of retained austenite (RA). The tempering temperature significantly influences proportion of RA and the mechanical properties. Therefore, the tempering temperature and the volume fractions of RA in through-hardened tool steels must be optimized to minimize dimensional variations and augment performance in service. In this work, the hardened samples were subjected to tempering process at different tempering temperatures and hardnes, impact and tensile tests were applied to the samples. Then the results obtained from these tests were analyzed and optimum tempering temperature was defined. The findings reveal that low-temperature tempering leads to a robust stabilization of the RA phase and better mechanical properties for the steel investigated.

Abstract

Bu çalışmada, temperleme sıcaklığı ve kalıntı östenit miktarının, sertleştirilme işlemine tabi tutulmuş 1.2842 (O2) soğuk iş takım çeliğinin mekanik özelliklerine etkisi araştırılmıştır. Sertleştirme ısıl işlemi sonrası uygulanan temperleme işlemlerinde sıcaklığı kalıntı östenit miktarını önemli derecede etkilemektedir. Bu nedenden ısıl işlemler sonrası istenilen mekanik özelliklerinin elde edilebilmesi için kalıntı östenit miktarı ve temperleme sıcaklığının optimize edilmesi gerekmektedir. Bu çalışmada, sertleştirilmiş ve farklı sıcaklıklarda temperleme işlemine tabi tutulmuş numunelerde elde edilen sertlik, tokluk, çekme dayanımı ve yüzde uzama değerlerini belirlemek için sırası ile sertlik, çentik darbe ve çekme testleri yapılmıştır. Bu testlerde elde edilen sonuçlar analiz edilerek optimum temperleme sıcaklığı belirlenmiştir. Deneylerden elde edilen sonuçlara göre 1.2842 soğuk iş takım çeliği için kalıntı östenit miktarının en olumlu etkisi ve en uygun mekanik özelliklerin düşük temperleme sıcaklığında olduğu gözlenmiştir.
