Özet: Al–6.5Ni–1.5Fe (wt.) alloy was directionally solidified upward at a constant growth rate (V = 16.57 µm/s) and with five different temperature gradients (G = 3.23–8.52 K/mm) by using a Bridgman type directional solidification furnace. In this way it was investigated effect of temperature gradient (G) on microstructure (λ) and microhardness (HV). The distance between microstructures and microhardness values were measured and the effect of temperature gradient on microstructure and microhardness was determined. The relationship between physical properties was determined by linear regression analysis and with the data obtained similar experimental results were compared.
