Effect of temperature and Al-5Ti-1B grain refiner on the tensile properties of commercially pure Aluminium

In the present investigation, the effect of Al-5Ti-1B grain refiner in bar and powder form with two different powder weight percent, as well as three different melting temperature on tensile properties of commercially pure Aluminium have been studied. Samples have been cast in two different gating system: From end of sample (Directional Solidification) and from middle of sample. Experimental temperatures selected as follows: 720,760 and 800 0C. A comparative study on tensile properties of commercially pure aluminium with grain refiner and without grain refiner was carried out. The aim of this study was to evaluate the yield stress values at various casting temperatures.
