Abstract (2. Language): 
In this study, steel sheet materials were used in order to obtain dual-phase steel. Specimens for this purpose have been annealed in ferrite + astatine regions at the temperatures of 740, 760, 800 and 820 °C. The specimens were annealed at the different temperatures with corresponding times 20, 40 and 60 minutes and quenched into water. As a result of this dual-phase steels at different ferrite + martensite ratio were produced. Sheet specimens were tested at the range of loading rates of 10, 50 and 259 mm/min. Strength properties of dual-phase steels were investigated depending on annealing temperature, ratio of martensite and loading rate.

Bu çalışmada, dual fazlı çelik elde etmek için çelik saç malzemeler kullanılmıştır. Deneysel çalışmaların gerektirdiği ölçülerde hazırlanan numuneler ferrit + ostenit bölgesinde farklı sıcaklıklarda (740, 760, 800, 820 °C) tavlanmışlardır. Herbir sıcaklıkta numuneler 20, 40 ve 60 dakika tavlama sürelerinde tavlanarak suda su verilmiştir. Seçilen tavlama programına bağlı olarak martenzit ve ferrit oranları farklı dual fazlı çelikler elde edilmiştir. Saç numuneler 10, 50 ve 250 mm/dak' lık yükleme hızlarında testlere tabi tutularak çekme dayanımları belirlenmiştir. Söz konusu dual fazlı çeliklerin çekme özellikleri tavlama sıcaklığına, martenzit oranına ve yükleme hızına bağlı olarak incelenmiştir.
