Abstract

Ürünün kullanım alanına bağlı olarak mekanik özelliklerin elde edilmesinde termomekanik haddeleme işlemi büyük önem taşımaktadır. Düşük karbonlu ve mikro alaşımlı çeliklerde yüksek mukavemet, sertlik ve tokluk değeri elde etmek için sıklıkla kullanılan bir haddeleme yöntemidir. Termomekanik haddeleme işlemi ile bobin üzerinde hem mekanik işlem hem de ısıl işlem yaparak mikroyapıyı değiştirmeye çalışır. Bu çalışmada, niyobyum ve titanyum alaşımlı çeliklerde termomekanik haddeleme sonrası mekanik özellikler ve mikro yapı değişiklikleri incelenmiştir.

Abstract

Thermomechanical rolling process is of great importance in obtaining mechanical properties depending on the area of use of the product. It is a frequently used rolling method in order to obtain high strength, hardness and toughness value in low carbon and micro alloy steels. With the thermomechanical rolling process, it tries to change the microstructure by performing both mechanical processing and thermal treatment on the coil. In this study, mechanical properties and microstructure changes after thermomechanical rolling in niobium and titanium alloy steels were investigated.
