Abstract
Bu çalışmada alüminyum alaşımlarının yönlü katılaştırılabilmesi için doğru sıcaklık kontrolü sağlayabilecek birdeney düzeneği kurulmuştur. Hazırlanan düzenek üzerinde sıcaklık kontrolünün sağlanabilmesi amacıylahareketli ısı bariyeri, soğutucu ısıtma fırını ve soğutma sistemi entegre edilmiştir. Deney düzeneğininkalibrasyonu için sıcaklık haritası çıkarılmıştır. Sıcaklık haritası sonuçlarına göre fırının farklı konumlarındakalıp içinde 2,5–4,8C/cm aralığında sıcaklık gradyan değerleri elde edilmiştir.
