AB  - This study reports the combinatorial influence of build direction and different ageing times. The Additively Fabricated (AF) with selective laser melting (SLM) specimens built-in various build directions (0o – 45o - 90o). Accordingly, Solution Heat Treatment (SHT) was applied then quenched in water at room temperature afterward. Subsequently, T4 and T6 ageing procedures were executed. Besides achieving advantageous T6 artificial ageing (AA), specimens were exposed to different time combinations (0.5, 1, 2, 6, 10 h). Although it was observed that the density did not change significantly with heat treatment, it was indicated that the hardness value decreased around 35% with the decrease in time, especially for T6 conditions. The microstructure disparity as a function of the utilized temperature, build direction, and time of the specimens were correlated to hardness values. It was observed that build direction and relative density results have no significant effect on the hardness.

N2  - Bu çalışmada, Eklemeli İmalat ile üretilmiş parçaların inşa yönü ve farklı yaşlandırma sürelerinin parça üzerindeki etkileri incelenmiştir. Seçici Lazer Ergitme yöntemi (SLE) ile 0o – 45 – 90o inşa yönlerinde üretilmiş numunelere daha sonra çözeltiye alma ısıl işlemi uygulanmıştır. Takiben oda sıcaklığında su verme işlemine tabii tutulmuştur. Ardından da T4 ve T6 yaşlandırma işlemleri uygulanmıştır T6 yapay yaşlandırma işleminin avantajlarını görebilmek için numunelere farklı sürelerde ısıl işlem uygulanmıştır. Isıl işlemle yoğunluğun önemli ölçüde değişmediği görülmekle birlikte, özellikle T6 koşulları için ısıl işlem süresinin artmasıyla birlikte sertlik değerinin %35 civarında azaldığı belirtilmiştir. Uygulanan sıcaklığın, inşa yönünün ve ısıl işlem sürelerinin bir fonksiyonu olarak mikro yapıdaki düzensizlikler incelenmiş ve sertlik değerleriyle ilişkilendirilmiştir. İnşa yönü ve yoğunluk sonuçlarının sertlik üzerinde önemli bir etkisinin olmadığı görülmüştür.
