[0126] [1. Manufacture of sample]
[0127] [1.1. Manufacture of powder for additive manufacturing]
[0128] The powder is produced by an atomization method using raw materials having a predetermined composition by blending. Next, except for Comparative Example 1, the powders thus obtained were subjected to oxidation treatment to form an oxide film having a predetermined thickness on the surface of the powders. Table 1 shows the respective compositions of the obtained powders for additive manufacturing (the balance being Fe and unavoidable impurities).

Description
technical field [0001] The present invention relates to powders for additive manufacturing and mold parts for molding, and in particular to powders for additive manufacturing capable of being smoothly conveyed in additive manufacturing equipment, and moldings obtained by additive manufacturing of powders for additive manufacturing mold parts. Background technique [0002] "Die casting" is a method in which molten metal is pressed into a mold, where it solidifies to create a casting. Die casting has the advantage that precision castings can be produced in large quantities in a short period of time. [0003] A typical mold for die casting has a cooling water circuit inside so that the molten metal pressed into the mold can solidify in a short time. The cooling water circuit is usually formed by machining such as cutting. In addition, during molding, the mold is repeatedly heated and cooled. [0004] Therefore, steel materials used for die casting molds are required to have...
