The samples were solidified under steady-state conditions with a constant growth rate of 8.20 mu m/s at different temperature gradients (1.97-6.84 K/mm) and with a constant temperature gradient (6.84 K/mm) at different growth rates (8.20-492.76 mu m/s). Microstructure parameters (primary dendrite arm spacing, lambda(1), secondary dendrite arm spacing, lambda(2), dendrite tip radius, R and mushy zone depth, d) were measured as a function of temperature gradient and growth rate. The experimental results have been compared with the current theoretical models and similar experimental works.eninfo:eu-repo/semantics/closedAccessAl-Si alloydirectional solidificationdendritic growthmicrostructuresArticle161122110.1007/s11665-006-9002-22-s2.0-84870948171Q2WOS:000244939300003Q4
