Abstract
Provided are: a semi-solidified slurry production method capable of obtaining a semi-solidified slurry having small variation of the solid phase ratio at each part, a molded body production method capable of reducing the variation of the size of crystal grains, and a molded body. The semi-solidified slurry production method comprises: a preparation step of placing a molten metal into a bottomed container; and a stirring step of stirring the molten metal by performing reciprocating movement of a rod placed in the molten metal in a length direction of the rod until a solid phase ratio at any portion of the molten metal in the container reaches 80% or more.
Claims6
A production method for a semi-solidified slurry including a solid phase and a liquid phase, the production method comprising:
- a preparation step of placing a molten metal into a bottomed container;
- and
- a stirring step of stirring the molten metal by performing reciprocating movement of a rod placed in the molten metal in a length direction of the rod until a solid phase ratio at any portion of the molten metal in the container reaches 80% or more.
A molded body which includes primary crystals and eutectic crystals, in which a fiber flow continuously exists, and which is made of a metal, wherein
- when a plurality of eutectic area ratios each of which is a ratio of an area of the eutectic crystals appearing in a field of view on a predetermined cross-section to an area of the field of view are measured for each field of view, a variation coefficient obtained by dividing a standard deviation of the eutectic area ratios by an average value of the eutectic area ratios is 0.15 or less.
