Abstract

It has been investigated how the electrical properties of the directionally solidified Al-13.6Cu-6Si alloy change depending on both the solidification rate and temperature, and how the thermal properties of the same alloy behave according to the temperature. Within the scope of this study, first of all, the electrical resistivity (ρ) measurements of the alloy were made with the four-point method and the temperature coefficient of the resistivity () was calculated. The relationship between thermal conductivity (K) and temperature (T) was determined with the experimental findings obtained using the Wiedemann−Franz and Smith-Palmer equations. In addition to enthalpy of fusion (H) and specific heat (cp) values, the melting temperature (TE) of the alloy was determined from the heat flow-temperature curve drawn by performing DSC analysis in the temperature range of 320-953 K.

Özet

Doğrusal olarak katılaştırılan Al-13.6Cu-6Si alaşımının elektriksel özelliklerinin hem katılaştırma hızına hem de sıcaklığa bağlı olarak nasıl değişim gösterdiği ve buna ek olarak yine aynı alaşımın termal özelliklerinin sıcaklığa göre nasıl bir davranış sergilediği araştırılmıştır. Bu çalışma kapsamında öncelikle alaşımın elektriksel özdirenç (ρ) ölçümleri dört nokta prob yöntemi ile yapılmış ve özdirencin sıcaklık katsayısı () hesaplanmıştır. Wiedemann−Franz ve Smith-Palmer denklemleri kullanılarak elde edilen deneysel bulgularla ısıl iletkenlik (K)-sıcaklık (T) arasındaki ilişki belirlenmiştir. 320–953 K sıcaklık aralığında DSC analizi yapılarak çizilen ısı akışı-sıcaklık eğrisinden entalpi (H) ve özısı (cp) değerlerine ek olarak alaşımın erime sıcaklığı da (TE) belirlenmiştir.
