Abstract
Sanayide alüminyum malzemelere olan ilgi gün geçtikçe artmaktadır, özellikle ağırlık azaltma hedeflerini yakalayabilmek için malzeme değişikliklerinin temelinde çelikten alaşımlandırılmış alüminyum malzemelere geçiş yer almaktadır. Alaşımlandırılmış alüminyumlar yüksek korozyon direnci gerektiren havacılık uygulamalarında da ağırlık azaltma yönünde ön plana çıkmaktadır. Yüksek mukavemet sağlayarak ürünlerin ömürlerinde de artış ile olumlu katkı sağlamaktadır. Bu çalışmada 12,7-28,6 mm arasında farklı çaplarda Al2024 T3 boru numunelere farklı büzme/çap azaltma işlemleri gerçekleştirilmiş ve T0, T42 ve kriyojenik ısıl işlemler uygulanmıştır. Büzme operasyonunun ürünlerin çap değişken parametresine göre deformasyon seviyeleri ölçülmüştür. Deformasyon yoğunluğunun arttığı ve bu artışın çekme dayanımı ve sertlik değerleri ile doğru orantılı olduğu gözlemlenmiştir. T3 ısıl işlemli borulara, T0-T42 ve kriyojenik ısıl işlem uygulamaları yapılmıştır. Bu uygulamalar ile mekanik dayanım, sertlik ve mikroyapı incelemeleri raporlanmıştır. Bu veriler ile büzme ve ısıl işlemin etkisi kıyaslanmıştır

Abstract
The interest in aluminum materials in the industry is increasing day by day, especially in order to achieve weight reduction targets, the basis for material changes is the transition from steel to alloyed aluminum materials. Alloyed aluminum also comes to the fore in terms of weight reduction in aviation applications that require high corrosion resistance. It contributes positively to the increase in the lifespan of the products by providing high strength. In this study, different swaging/diameter reduction processes were performed on Al2024 T3 pipe samples with different diameters between 12.7-28.6 mm and T0, T42 and cryogenic heat treatments were applied. Deformation levels of the swaging operation were measured according to the diameter variable parameter of the products. It has been observed that the deformation intensity increases and this increase is directly proportional to the tensile strength and hardness values. T0-T42 and cryogenic heat treatment applications were applied to T3 heat treated pipes. Mechanical strength, hardness and microstructure investigations were reported with these applications. The effects of swaging and heat treatment were compared with these data.
