Hastelloy C276/UNS S32205 Malzeme Çiftinin Birleştirilmesinde ER 316 L İlave Metal Kullanımının Mikroyapı ve Mekanik Özelliklere Etkisi
Bu çalışmada, Hastelloy C276 nikel bazlı süper alaşım ile UNS S32205 dubleks paslanmaz çelik benzer olmayan malzeme çifti, MAG (metal aktif gaz) yöntemi ve ER 316L ilave metali kullanılarak birleştirilmiştir. Kullanılan ilave metalin kimyasal özellikleri her iki ana malzemenin mekanik ve kimyasal özelliklerinden farklıdır. Kaynaklı bağlantının genel mikro yapısı optik mikroskop ile incelenmiştir. Benzer olmayan birleştirmenin, ergime sınırlarında meydana gelen geçiş bölgesinin elementel karakterizasyonu yapılarak, bu bölgede seyrelme sonucu meydana gelen değişimler elementel haritalama ile açıklanmıştır. İlave metalin Nikel içeriği nedeni ile tüm çentik darbe testi numunelerinde yüksek tokluk değerleri elde edilmiştir
