Assessment of the effect of grain refinement on the solidification characteristics of 319 aluminum alloy using thermal analysis
چکیده انگلیسی
The effect of different amount of Al-5Ti-1B grain refiner on the macro and microstructural features and characteristic parameters of the cooling curve of 319 aluminum alloy were studied using thermal analysis. Important parameters in liquidus, eutectic Si and eutectic Cu-phase regions have been calculated using the first derivative cooling curves. The results indicated that, the solidification parameters such as nucleation and growth temperatures of various phases, undercooling temperatures, solidification range and total solidification time were affected by grain refining. Also, latent heat and fraction solid were determined for the different amount of grain refiner for 319 alloy. It has been found that the fraction solid is completed fast by addition of Al-5Ti-1B grain refiner.
