An investigation on microstructures and refining performances of newly developed Al-Ti-C grain refining master alloys

While preparing Al-Ti-C master alloys, grain refiners are added to molten aluminum before casting to produce fine grain structures in the solidified ingots or cast products. Grain refining improves the properties of master alloys. The phases and microstructures of master alloys were analyzed using X-ray phase analysis and scanning electron microscopy.
