Zusammenfassung: | The present invention relate to a novel metal composite. According to the present invention, the metal composite has at least two or more crystalline phases or crystal structures at room temperature in accordance with the regulation, in a specific range, of amounts of magnesium, aluminum, titanium, iron or zinc, and, particularly, the metal composite further has a hexagonal closed packed (hcp) structure, in addition to a face centered cubic (fcc) structure and a body centered cubic (bcc) structure, thereby enabling the economical manufacture thereof and having effects of exhibiting excellent ductility and toughness while maintaining suitable hardness.
La présente invention concerne un nouveau composite métallique. Selon la présente invention, le composite métallique possède au moins deux phases cristallines ou structures cristallines à température ambiante, suivant la régulation, dans une plage spécifique, de quantités de magnésium, d'aluminium, de titane, de fer ou de zinc. En particulier, le composite métallique présente en outre un réseau hexagonal compact (hcp), en plus d'une structure cubique à faces centrées (fcc) et d'une structure cubique centrée (bcc), ce qui permet de le fabriquer de manière économique tout en lui conférant une excellente ductilité et une excellente ténacité, en conservant par ailleurs une dureté appropriée.
본 발명은 신규한 금속 복합체에 관한 것이다. 본 발명에 따른 금속 복합체는 마그네슘, 알루미늄, 티타늄, 철 또는 아연의 함량을 특정 범위로 조절함에 따라 상온에서 적어도 2 이상의 결정상 또는 결정 구조를 갖고, 특히 상기 금속 복합체가 면심 입방 결정구조(fcc) 및 체심 입방 결정구조(bcc) 이외에 추가로 조밀육방 결정구조(hcp)를 가짐으로써 경제적으로 제조가 가능할 뿐만 아니라 적절한 경도를 유지하면서도 우수한 연성 및 인성을 나타내는 효과가 있다. |
