摘要:

鎂及其合金是目前工程應用中最輕的結構金屬，在航空航天、國防軍工、交通運輸以及3C電子等領域具有廣泛的應用前景，對于促進國家“雙碳”戰略、保障經濟建設與國防安全有著重要作用。加工成型工藝是鎂產品制備與鎂產業發展的重要一環，常用的鎂合金加工方法主要包含了液態成形、固態成形、增材制造、焊接等，目前產業發展存在著能耗高、經濟性低、穩定性與均勻一致性差的問題，如何從源頭解決成分均勻控制難題、提升加工經濟性與穩定性是獲得高品質鎂合金的關鍵，而其內在科學問題是掌握加工過程中的微納組織演變規律、強韌化機制，明晰成形缺陷的成因、演化規律，掌握合金成分高效檢測及精準調控方法，基于此，可有效實現鎂產品的高效低成本制造，并建立相關的測試評價標準。

Abstract:

Magnesium (Mg) and its alloys are currently the lightest structural metals in engineering applications, with broad application prospects in fields such as aerospace, defense and military industry, transportation, and electronic 3C. They play an important role in promoting the national dual carbon strategy, ensuring economic construction, and national defense security. Processing and forming technologies are an important part of the development and application of the magnesium industry. The commonly used processing technologies mainly include casting, forging, additive manufacturing, welding, etc. At present, there are problems with high energy consumption, low economic efficiency, poor stability and uniformity in industrial development. The key to fabricate the high-quality Mg alloys is to solve the problem of uniform control of composition, improve processing economy and stability. The scientific problem is to grasp the evolution laws of micro and nano structures, explicit the strengthening and toughening mechanisms during the processing, clarify the causes and evolution laws of forming defects, master the efficient detection and precise regulation methods of alloy components. Based on these, we can realize the low�瞔ost manufacturing of Mg products with high efficiency, and establish relevant testing and evaluation standards.
