摘要:

高端制造等行業對特殊鋼的性能需求日益提升，這對特殊鋼的研發和更新換代速度提出了極高的挑戰。基于傳統試錯法的研發方式雖然可在部分問題上避開未知物理機理的限制，但同時也會導致設計所需時間和成本的大量消耗。因此，特殊鋼的研發方式需要逐漸從傳統試錯法向計算設計到實驗驗證模式轉變。“材料基因組計劃”自問世以來，在諸多材料體系的設計上都發揮了顯著的作用，但在傳統結構材料尤其是鋼鐵材料上，由于其合金體系的復雜性、工藝流程的長鏈條、組織的多樣性以及性能的多目標需求，使其成為材料基因工程的難點。但正基于上述特點，傳統結構材料也為材料基因工程提供了發揮的空間，世界各國紛紛開展特殊鋼方面的高通量計算與設計。通過對基于材料基因思想的特殊鋼研發進展的綜述，評價了針對特殊鋼的材料基因工程發展現狀及未來方向。介紹了美國西北大學Olson團隊以及Questek公司通過多尺度集成計算平臺研發的飛機起落架用超高強不銹鋼、荷蘭代爾夫特大學通過“基因”設計理念結合高通量遺傳算法設計的高性能耐熱鋼、印度CSIR國家冶金實驗室通過多種本構模型結合人工神經網絡進行的高性能管線鋼設計等。特殊鋼的高通量計算與設計研究不但可以促進特殊鋼的更新換代，更會為我國乃至世界金屬材料的高速發展提供支撐與保障。

Abstract:

The demand for special steel in the high�瞖nd manufacturing industry poses a great challenge to the development and upgrading of special steel. The trial-and-error method can avoid the limitation of unknown physical mechanism on some problems, but it also takes a large amount of both time and cost of designing. So the development mode of special steel needs to gradually transform from traditional trial-and-error method to high flux integrated computing design. Since the advent of the materials genome initiative (MGI), many countries in the world have been carrying out high�瞭hroughput calculation and design of special steel to shorten the research and development cycle of new steels. However, the complicated composition, long chain of process, multi-phase structure and various properties make it difficult to apply MGI on traditional special steels. Based on the above characteristics, it also provided new challenges for the development of MGI. The progress in research and development of special steels based on MGI was reviewed. The development status and prospect of MGI for special steel materials were discussed. Olson‘s team in Northwestern University and Questek company designed the ultra-high strength stainless steel for aircraft landing gear using multi-scale integrated computing platform. TU Delft university designed the heat-resistant steel based on combining “genome” concept with genetic algorithm of high throughput design. India CSIR national metallurgical laboratory designed the pipeline steel by a variety of constitutive models and artificial neural network algorithms. High-throughput calculation and design can not only facilitate the updating of special steel, but also provide supports for the rapid development of metal materials in China and even worldwide.
