Experimental Investigation of Stretchability and Bendability Characterization of AISI 1020 Steel

Öz

In this study formability of AISI 1020 steel sheet with different thicknesses was investigated by limiting dome height test at room temperature. The influence of thickness on the stretchability, bendability characteristics and dome height for AISI 1020 steel sheets had been identified from experimental data. Increase in the thickness enhanced stretchability, bendability characteristics and dome height values. Results of experiments indicate that AISI 1020 steel sheets can be used to product components with manufacturing processes based on bending and stretching.

AISI 1020 Çeliğinin Gerilebilirlik ve Eğilebilirlik Özelliklerinin Deneysel Olarak İncelenmesi

Öz

Bu çalışmada, farklı kalınlıklardaki AISI 1020 çelik sacın şekil verilebilirliği, oda sıcaklığında tepe yüksekliği testi kullanılarak araştırılmıştır. AISI 1020 çelik levhalarda kalınlığın; gerilebilirlik, eğilebilirlik karakteristikleri ve tepe yüksekliği üzerindeki etkileri deneysel verilerden tespit edilmiştir. Sac kalınlığındaki artış gerilebilirlik, eğilebilirlik karakteristikleri ve tepe yüksekliği değerleri üzerinde olumlu etki göstermiştir. Deney sonuçları, AISI 1020 çelik sacların gerdirme ve eğme esaslı imalat yöntemlerinde kullanılabileceğini göstermektedir.
