Abstract
A thixotropically molded product includes: a matrix portion containing Mg as a main component; a first particle portion dispersed in the matrix portion and containing SiC as a main component; a second particle portion dispersed in the matrix portion and containing Mg2Si as a main component; and a third particle portion dispersed in the matrix portion and containing MgO as a main component. An area fraction of the first particle portion in a cross section is 0.68 or more and 19.6% or less.

A thixotropically molded product comprising:
- a matrix portion containing Mg as a main component;
- a first particle portion dispersed in the matrix portion and containing SiC as a main component;
- a second particle portion dispersed in the matrix portion and containing Mg2Si as a main component;
- and
- a third particle portion dispersed in the matrix portion and containing MgO as a main component, wherein
- an area fraction of the first particle portion in a cross section is 0.6% or more and 19.6% or less.
A thixotropic molding material comprising:
- a metal body containing Mg as a main component;
- silicon carbide particles adhering to a surface of the metal body and containing SiC as a main component;
- and
- interposed particles interposed between the metal body and the silicon carbide particles and made of an inorganic material, wherein
- a ratio of the silicon carbide particles to a total of the metal body and the silicon carbide particles is 1.0 mass % or more and 30.0 mass % or less.
A method of producing a thixotropic molding material comprising:
- a preparation step of preparing a mixture containing a metal body containing Mg as a main component, silicon carbide particles containing SiC as a main component, interposed particles made of an inorganic material, and a dispersion medium;
- a stirring step of stirring the mixture;
- and
- a drying step of adhering the silicon carbide particles to a surface of the metal body via the interposed particles by removing at least a part of the dispersion medium from the stirred mixture, wherein
- in the mixture, a ratio of the silicon carbide particles to a total of the metal body and the silicon carbide particles is 1.0 mass % or more and 30.0 mass % or less.
