Control on the density of multi-grains during solidification in Al-based alloys

摘要

The present invention is adjusted according to the fine polycrystalline grain size during solidification of aluminum alloy, aluminum alloy solidification unit (solidification) in the immobilization device to, radiation incident on the solid-phased supply means and the radiation beam chair aluminum alloy, the aluminum alloy by a rotational force through the temperature control inside the solid and rotating means for rotating crystallized Bridgman and When the radiation received from the radiation supplying means supply passes through the aluminum alloy and comprises a recording means for recording the particle structure to obtain this, check the image of the aluminum alloy obtained by the photographing means by controlling a rotation Bridgman characterized by determining a particle of an aluminum alloy. The present invention has the advantage that the above structure can be easily hwahal solid phase according to the crystal grains to be won can be immobilized in real time while checking the particle structure of aluminum alloy.
