摘要： PROBLEM TO BE SOLVED: To provide a method of preparing semi-solid slurry, which can easily prepare semi-solid slurry or a semi-solid molding in a short time without being restricted to a type/composition of a target metal, and a semi-solid molding.
SOLUTION: When a metal in a molten state is poured into a container or a sleeve (which is referred to as a "container or the like" hereinafter), pouring is carried out in such a manner that the metal enters a supercooled state without generating an initial solid layer and self-mixing occurs in the container. Nuclei are generated without producing an initial solid layer by a supercooling phenomenon which occurs by bringing the molten metal into contact with a cooling container or a cooling portion from a fixed height, and then mixing is carried out to eliminate a temperature gradient in the cooling container or in the cooling portion, thereby providing a semi-solid state.

摘要： PROBLEM TO BE SOLVED: To provide an Ni based alloy in which macro componential segregation can be suppressed as far as possible by controlling a cast structure with a trace amount of inclusions, and to provide a method for producing the same.
SOLUTION: Disclosed is the Ni based alloy having a componential composition comprising 0.01 to 0.7 mass% Ti and 5 to 100 ppm oxygen, and the balance Ni with inevitable impurities, and in which a Ti oxide is comprised as a nonmetallic inclusion. Also disclosed is a method for producing the Ni based alloy, by which a raw material is melted in an Ar atmosphere so as to obtain a melted alloy, 0.1 to 1 mass% Ti is added to the melted alloy so as to produce a Ti based oxide, and the Ti based oxide is cast into a mold and is cooled so as to be a steel ingot.
