Consider a bicrystalline alloy undergoing solidification in a controlled envi- ronment. The alloy consists of two distinct crystal phases, each with unique solidification properties. The solidification process is characterized by the formation of dendritic structures, which are influenced by the temperature gradient and the velocity of the solidification front. The alloy is similar to a succinonitrile-0.4 wt.% acetone alloy, undergoing solidification in a fixed temperature gradient of 10 K/cm, moving at a velocity of 25 µm/s. Task Dendritic Growth Analysis Calculate the velocity of the solid-liquid interface in the alloy using the given temperature gradient and solidification parameters. Consider the latent heat released during solidification and its impact on the interface velocity. Heat Flow Dynamics Analyze the heat flow dynamics around the dendritic structures, particularly focusing on the temperature inversion in the liquid near the interface and its effect on dendrite growth. Microstructural Prediction Based on phase field theory, predict the evolution of the dendritic microstruc- ture in the bicrystalline alloy over time. Consider factors such as crystal- lographic orientation, secondary arm blocking, and the development of a steady-state growth morphology. Implications for Mechanical Properties Discuss how the dendritic microstructure, specifically the density and orien- tation of the dendrites, might affect the mechanical properties of the solidified alloy, such as strength and ductility. Constraints Assume standard pressure conditions. Consider the properties of succinonitrile-0.4 wt.% acetone alloy as a reference for your calculations. Ignore gravitational effects.
