Mg ve Ti ilaveli Al Alaşımlarının Çekme Mukavemetinin Optimizasyonu

Bu çalışmada, alüminyum alaşımlarının çekme mukavemetine magnezyum ve titanyum elementlerinin etkisi araştırılmıştır. Alaşımlar kum döküm yöntemi ile üretilmişlerdir. Alaşımlarda, magnezyum oranı ağırlıkça %2-14, titanyum %1-3 oranında değişmektedir. Çekme testler oda sıcaklığında 1 mm/dak hızında yapılmıştır. Yapay sinir ağları yöntemi kullanılarak alaşımların çekme mukavemeti araştırılmıştır. Eğitim ve test sonuçlarının liner korelasyonu %99,12 ve %91,88 olarak tespit edilmiştir. Alaşımların çekme mukavemeti üzerine magnezyumun, alüminyumdan ve titanyumdan daha büyük bir etkiye sahip olduğu görülmüştür.

Optimization of Tensile Strength of Al Alloys with Mg and Ti

In this study, the influences of magnesium and titanium elements on the ultimate tensile strength of aluminum alloys were analyzed. The alloys were produced with sand casting method. Magnesium and titanium contents in the alloys were varied from 2 to 14 wt.% and from 1 to 3 wt.%, respectively. Tensile tests were carried out at a tensile speed of 1 mm/min and room temperature. The tensile strength of these alloys was also investigated using the artificial neural network approach. Linear correlations of train and test results were observed to be 99.12 and 91.88%, respectively. It was seen that magnesium has a greater effect than aluminum and titanium on the tensile behavior.
