摘要:

隨著全球能源危機和環(huán)境危機加劇，高性能輕質(zhì)節(jié)能材料和新型儲能材料的研發(fā)和規(guī)模應(yīng)用需求日益緊迫。鎂合金作為最輕的金屬結(jié)構(gòu)材料，應(yīng)用于軌道交通、航空航天可顯著地節(jié)能減排，且綠色高安全性的鎂基儲能材料也有著巨大的應(yīng)用前景。特別地，鎂及鎂合金是我國的優(yōu)勢材料資源，拓展鎂合金的廣泛應(yīng)用具有重要的戰(zhàn)略意義。但目前高性能鎂合金牌號明顯偏少，依靠實驗開發(fā)為主的現(xiàn)狀嚴(yán)重影響了鎂合金更大規(guī)模的推廣應(yīng)用。關(guān)鍵熱力學(xué)動力學(xué)基礎(chǔ)信息是高性能鎂合金設(shè)計與應(yīng)用的基礎(chǔ)和必要信息。然而，相較于鋼鐵、鋁合金及鈦合金等，鎂合金的熱力學(xué)與動力學(xué)基礎(chǔ)數(shù)據(jù)和數(shù)據(jù)精度均相當(dāng)有限，這成為制約傳統(tǒng)鎂合金材料優(yōu)化、新型高性能鎂合金材料高效智能研發(fā)和鎂合金大規(guī)模快速應(yīng)用的瓶頸問題。為此，系統(tǒng)地研究多元鎂合金的關(guān)鍵熱力學(xué)動力學(xué)基礎(chǔ)數(shù)據(jù)、合金元素間的交互作用特征及交互作用機理，構(gòu)建系統(tǒng)的、高精度的多元鎂合金熱力學(xué)和動力學(xué)數(shù)據(jù)庫，是推動高性能鎂合金材料智能設(shè)計和促進(jìn)鎂合金更大規(guī)模應(yīng)用的關(guān)鍵路徑之一。

Abstract:

With the intensification of the global energy crisis and environmental crisis, the development and large-scale application demand of high-performance lightweight energy-saving materials and new energy storage materials are becoming increasingly urgent. Magnesium alloys, as the lightest metal structure material, can be energy saving and emission reduction when applied to rail transportation and aerospace. Furthermore, the green and highly secure magnesium-based energy storage materials also show great application prospects. Especially, magnesium and its alloys are the advantageous material resources in China, and thus expanding the wide application of magnesium alloys is of great strategic significance to our country. However, the number of high-performance magnesium alloy grades is obviously small at present. The traditional experimental development severely hinders the promotion and application of magnesium alloys on a larger scale. The key basic data of thermodynamic and kinetics is of extreme importance and necessity for the design and application of high-performance magnesium alloys.Nevertheless,the thermodynamic and kinetics data and data accuracy of magnesium alloys are both quite limited, in comparison with those of steel, aluminum alloys and titanium alloys, etc. It has become a key bottleneck point restricting the optimization of traditional magnesium alloys, the efficient and intelligent development of new high-performance magnesium alloys, and the large�瞫cale application of magnesium alloys. Therefore, systematic research on the key basic data of thermodynamic and kinetic of multivariate magnesium alloys, the interaction characteristics and interaction mechanism between alloying elements, and the construction of a systematic high-precision thermodynamic and kinetic databases for multivariate magnesium alloys are one of the key paths to promote the intelligent design of high-performance magnesium alloys and the application of magnesium alloys on a larger scale.
