Zusammenfassung:Directional solidification experiments have been carried out on different Pb-Sn alloys as a function of temperature gradient G, growth rate V and cooling rate GV. The specimens were solidified under steady state condition with a constant temperature gradient (50 °C/cm) at a wide range of growth rates ((10–400) × 10−4 cm/s) and with a constant growth rate (17 × 10−4 cm/s) at a wide range of temperature gradient (10–55 °C/cm). The primary dendrite arm spacing, λ1, and secondary dendrite arm spacing, λ2, were evaluated. This structure parameters were expressed as functions of G, V and GV by using the linear regression analysis. The results were in good agreement with the previous works.
