dc.description.abstractThe Sn-10.2 Sb (mass fraction) peritectic alloy was prepared using a vacuum melting furnace and a hot filling furnace. The samples were directionally solidified upwards at steady state conditions with a constant temperature gradient (G = 4.5 +/- 0.2 K. mm(-1)) under different growth velocities (V = 13.3-266.7 mu m. s(-1)) in a Bridgman-type directional solidification apparatus. The effects of the growth velocity (V) on the dendritic spacings were investigated. Primary dendrite arm spacing (PDAS) of a phase in directionally solidified Sn-10.2 Sb peritectic alloy was measured on the longitudinal and transverse sections of 4 mm diameter cylindrical samples. Secondary dendrite arm spacing (SDAS) was measured on the longitudinal section. The experimental results show that the measured PDAS (lambda(IL),lambda(IT)) and SDAS (lambda(2)) decrease with increasing growth velocity. The dependence of PDAS, SDAS, microhardness (HV) and compressive strength (sigma(c)) on the growth velocity were determined by using a linear regression analysis. The experimental results were compared with the previous experimental results and the results of the experimental models.
