dc.description.abstractAl-1.9Mn-5Fe (wt.%) alloy was prepared by adding 5 wt.% Fe to the eutectic Al-Mn alloy. This alloy undergone controlled solidification under four different growth velocities (V) in Bridgman-type furnace. Eutectic spacings (lambda), microhardness (HV), ultimate tensile strength (sigma(U)) and electrical resistivity (rho) of these alloys were determined. While the HV and sigma(U) increased with increasing V values or decreasing lambda, the elongation (delta) values decreased. In addition, relationships between these parameters were investigated using linear regression analysis. Microstructure photographs of directionally solidified samples were taken by optical microscope and scanning electron microscope (SEM). The eutectic spacings were measured from these photographs. The relationships among growth velocity (V), eutectic spacing (lambda), microhardness (HV), ultimate tensile strength (sigma(U)) and electrical resistivity (rho) were measured by suitable method and tests. The rho measurements were carried out depending on V and temperature (T). While temperature coefficient of resistivity (alpha(TCR)) was calculated from the rho-T curve, the values of thermal conductivity (K) predicted by Wiedemann-Franz (W-F) and Smith-Palmer (S-P) equations. It was found that the microstructure, microhardness, tensile strength and electrical resistivity were affected by both eutectic spacing and the growth velocity.
