"Including the case. In addition, when a part "includes" a certain component, it means that other components may be further provided, rather than excluding other components unless specifically stated to the contrary.

Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as "comprise" or "have" are intended to designate the presence of features, numbers, steps, actions, components, parts, or a combination thereof described in the specification, but one or more other features. It is to be understood that the presence or addition of elements or numbers, steps, actions, components, parts, or combinations thereof, does not preclude in advance.

In the present specification, hot isostatic pressing means molding by hot isostatic pressing, and is one of the powder metallurgy molding techniques.

In the hot isostatic pressing, a molded article is formed by simultaneously applying a high temperature of about 100°C to 2,000°C and an isotropic pressure of about 10 MPa to 200 MPa using a gas such as argon as a pressure medium.

The hot isostatic pressing is distinguished from a hot press method in which a material is processed using uniaxial pressure in that equal pressure is applied to the material from all directions, and all surfaces of the object to be treated contract equally.

The HIP molding is characterized by uniform pressure acting on the object to be processed, the shape after pressing does not change significantly from the shape of the initial object to be processed, and relatively few restrictions on the material of the object to be processed.
