| Abstract: | In this study, an Al–3.5Fe–2.5Ni hypereutectic alloy was produced by the Controlled Diffusion Solidification (CDS) process. The effectiveness of the technique on refining primary phases was confirmed in complex Al alloy systems. The results exhibited that the primary phase has the most significant refinement at a mass ratio of the high/low temperature melts equal to 4 and superheat equals to 5 °C, reducing the average length from approximately 200–48 μm and achieving a remarkable 75% refinement rate. Thermal and electrical conductivities increased from 165.2 W/(m·K) and 23.72 MS/m to 184.6 W/(m·K) and 24.59 MS/m, respectively. The tensile strength is increased to 170 MPa, improving by 40%. The hot tearing sensitivity value has been reduced from 162 to 50. By taking the advantages of mixing two precursor melts, the CDS process leads to a reduction of dendritic formations and an increase in non-dendritic the primary phase structure. The refinement for primary phase is the main reason for the improvement of the thermo-physical properties. [ABSTRACT FROM AUTHOR] |
