Abstract: A member includes a first metallic region made of a first material; a second metallic region made of a second material that is a different from the first material; and a mix region made of mixture of the first and second materials between the first and second metallic region. In a cross-sectional view, an interface between the first metallic region and the mix region is represented by a line having a first curved line protruding toward the first metallic region and a second curved line protruding toward the first metallic region, and an angle at a cross point of the first and second curved lines, the angle being made by a tangent line of the first curved line and a tangent fine of the second curved line in a region of the first metallic region, is equal to or larger than 70 degrees and smaller than 180 degrees.

Abstract: A method for manufacturing an additively manufactured body, which can suppress the occurrence of defects in the additively manufactured body, comprising: an additive manufacturing step of shaping an additively manufactured body in a heating state; and a machining step of machining the additively manufactured body in a state in which the heating state is maintained. The additively manufactured body can be shaped by the additive manufacturing step and the machining step which are repeated a plurality of times. The heating state is maintained also in the additive manufacturing step and the machining step which are repeated a plurality of times.
