Abstract
Official abstract text for this publication.
Provided is an article that includes silicon carbide as a main component and that has sufficient mechanical strength while manufactured by a three-dimensional shaping technology. The article that includes silicon carbide as a main component includes: silicon carbide; a metal boride having a melting point lower than a sublimation point of silicon carbide; and metal silicon.
First claim
Opening claim text (preview).
What is claimed is: 1 . An article comprising: silicon carbide; a metal boride having a melting point lower than a sublimation point of silicon carbide; and metal silicon. 2 . The article according to claim 1 , wherein the metal boride comprises at least any one selected from the group consisting of chromium diboride, vanadium diboride, and chromium monoboride. 3 . The article according to claim 2 , wherein the metal boride is chromium diboride, and wherein the article has a molar ratio between silicon carbide and chromium diboride, silicon carbide:chromium diboride, falling within a range of from 90:10 to 35:65. 4 . The article according to claim 1 , wherein the metal boride has a three-dimensional network structure. 5 . The article according to claim 1 , wherein the article has a porosity of 1% or less. 6 . A method of manufacturing an article comprising: forming a shaped object by repeating: forming a powder layer through use of mixed powder of powder containing silicon carbide and powder containing a metal boride having a melting point lower than a sublimation point of silicon carbide; and simultaneously scanning and irradiating the formed powder layer with an energy beam based on shape data of an object to be shaped to melt and solidify the powder containing silicon carbide and the powder containing a metal boride having a melting point lower than a sublimation point of silicon carbide; and further impregnating the shaped object with metal silicon. 7 . The method of manufacturing an article according to claim 6 , wherein the metal boride comprises at least any one selected from the group consisting of chromium diboride, vanadium diboride, and chromium monoboride. 8 . The method of manufacturing an article according to claim 7 , wherein the metal boride is chromium diboride, and wherein the article has a molar ratio between silicon carbide and chromium diboride, silicon carbide:chromium diboride, falling within a range of from 90:10 to 35:65.
