Effects of Tempering Heat Treatment Temperatures on Mechanical Properties of Carbon Steels

Year 2021, Volume: 7 Issue: 1, 17 - 25, 30.04.2021

Abstract

In the present study, the effects of tempering heat treatment temperatures on the mechanical properties of AISI 1020 and 1040 carbon steel types, which have a wide range of use in industry, were investigated. The samples were quenched at 850 °C, and then they were tempered at three different temperatures; 450, 550, and 650 °C, for 1 hour. Hardness measurements of the samples were performed to determine their mechanical properties. Besides, the samples were subjected to tensile and charpy impact tests. The samples were examined microstructurally, as well. The results reveal that the hardness, tensile strength, and yield strength values of both samples decreased when tempering heat treatment was applied after quenching. As the tempering temperature increased, these values tended to decrease. However, the impact value increased with the tempering heat treatment and increasing tempering temperature

Temperleme Isıl İşlem Sıcaklıklarının Karbonlu Çeliklerin Mekanik Özelliklerine Etkileri

Year 2021, Volume: 7 Issue: 1, 17 - 25, 30.04.2021

Abstract

Bu çalışmada, temperleme ısıl işlem sıcaklıklarının endüstride geniş bir kullanım alanına sahip olan AISI 1020 ve 1040 karbon çeliklerin mekanik özellikleri üzerine etkileri araştırılmıştır. Numuneler 850 ° C'de su verme işleminin ardından 450, 550 ve 650 ° C olmak üzere üç farklı sıcaklıkta 1 saat süre ile temperlenmiştir. Numunelerin mekanik özelliklerini belirlemek için sertlik ölçümleri, çekme ve çentik darbe testleri yapılmıştır. Ayrıca numuneler mikroyapısal olarak da incelenmiştir. Sonuçlar, su verme işleminden sonra temperleme ısıl işlemi uygulandığında her iki numunenin sertlik, çekme dayanımı ve akma dayanımı değerlerinin düştüğünü ortaya koymaktadır. Temperleme sıcaklığı arttıkça, bu değerler düşme eğiliminde olmuştur. Ancak, temperleme ısıl işlemi ve artan temperleme sıcaklığı ile darbe değerleri artmıştır.
