The directional solidification experiment of Al-Bi immiscible alloys has been carried out by using the self-made equipment with the applied magnetic field.

The elevated-temperature resistivity of Cu-Bi-Al alloy at different temperatures were measured by seebeck resistivity tester.

Preparation of Homogeneous Al-Bi Immiscible Alloy by a Cooling Slope Method;

Prepare the Homogeneous Al Based Immiscible Alloys by a Cooling Slope Method;

The directional solidification experiment has been carried out for the Al-Bi based immiscible alloys.

Considering the common action of minority phase spheres nucleation,diffusion growth,spatial movement and interaction between solidification interface and minority phase spheres,a model was developed to describe the kinetics of metastable liquid-liquid phase transformation and microstructure evolution in the metastable immiscible alloys with different volume fractions of minority phase spheres.
