Alloy Solidification

With the methods of macrostructure observation and temperature measurement, the paper has studied the influence rules of static magnetic field on 2024 aluminum alloy solidification structure and solidification rate. The conclusions can be concluded as follows: the static magnetic field can inhibit the growth of columnar crystals and promote the growth of equiaxed crystals; when the magnetic flux density is increased, the grain refining effect is better, the solidification rate of 2024 aluminum alloy increases remarkably, and the full solidification time is shorter; the reasons of grain refinement may be that the thermo-electromagnetic convection effect related to Peltier effect is stronger than electromagnetic braking effect, which can enhance the heat transfer and fluid flow in the solidification front, and that undercooling temperature is enlarged.

The paper has established a two-dimensional non-steady-state heat transfer model for 2024 aluminum alloy solidification process under the static magnetic field. According to the measured temperature and the inverse heat transfer problem, the boundary conditions of model have been determined, the results show that the solidification rate and heat flux acting on the ingot surface increase with increasing of the static magnetic filed strength; when the static magnetic filed strength become stronger, the isotherm location will move towards the liquid pool center, and the temperature gradient in the liquid metal pool will increase.
