In this work, effect of bearing length on tensile strength was investigated. The influence of the bearing length is illustrated using two different reduction ratios and wire diameters. According to the results, the increase in strength was observed as the length of the bearing zone increased. However, the long bearing length caused various manufacturing problems during production. Microhardness distributions in wire cross section, on the other hand, increased as the length of bearing increased. The main reason for the increase of microhardness is the deformation hardening caused by the high friction force obtained by increasing the bearing length.

Tel Çekme İşleminde Kalıp Kalibrasyon Bölgesi Uzunluğunun 1045 Çelik Tel Mukavemeti Üzerine Olan Etkisinin İncelenmesi
Öz
Bu çalışmada, tel çekme işleminde kalibrasyon uzunluğunun çekme mukavemeti üzerine olan etkisi incelenmiştir. Kalibrasyon bölgesinin etkisini iki farklı redüksiyon oranı ve filmaşin çapı kullanılarak gösterilmiştir. Elde edilen sonuçlara göre, kalibrasyon bölge uzunluğu arttıkça mukavemet artışı gözlemlenmiştir. Ancak, kalibrasyon boyunun uzun olması üretim esnasında çeşitli imalat problemlerine sebebiyet vermiştir. Çapsal mikrosertlik dağılımları ise kalibrasyon boyu arttıkça aralarındaki farklarda da artış gözlemlenmiştir. Mikrosertliğin artmasının esas sebebinin kalibrasyon boyunun artmasıyla elde edilen yüksek sürtünme kuvvetinin oluşturduğu deformasyon sertleşmesidir.
