Abstract: 기계적 특성과 내식성을 갖춘 마그네슘 합금 부재와 이 마그네슘 합금 부재의 제조 방법을 제공한다.
마그네슘 합금 부재는 마그네슘 합금으로 이루어지는 기재와, 이 기재 상에 형성된 방식(防蝕) 피막을 구비한다. 기재는, Al을 5 질량% 내지 11 질량% 함유하는 압연된 마그네슘 합금이다. 다량의 Al을 함유하는 기재를 이용함으로써, 기계적 특성이 우수하고, 내식성도 높은 마그네슘 합금 부재를 제조할 수 있다. 또한, 압연재를 이용함으로써, 주조 시의 표면 결함의 수가 적고, 언더코팅 처리 및 퍼티 매립(puttying)과 같은 보수 작업의 횟수를 줄일 수 있다.-

Abstract: To provide a method for producing a magnesium alloy plate which can be suitably employed for producing a magnesium alloy plate excellent in the plastic workability such as press workability. A method for producing a magnesium alloy plate according to the present invention relates to a method for rolling a magnesium alloy raw sheet by a rolling roll. The rolling includes a controlled rolling which is carried out under the following conditions (1) and (2), where M (mass %) represents an aluminum content of a magnesium alloy constituting the raw sheet: (1) a surface temperature of the magnesium alloy raw sheet (Tb, °C) immediately before the insertion to the rolling roll satisfying the following formula: 8.33 x M + 135
