摘要:

高端制造等行業(yè)對(duì)特殊鋼的性能需求日益提升，這對(duì)特殊鋼的研發(fā)和更新?lián)Q代速度提出了極高的挑戰(zhàn)�；�于傳統(tǒng)試錯(cuò)法的研發(fā)方式雖然可在部分問題上避開未知物理機(jī)理的限制，但同時(shí)也會(huì)導(dǎo)致設(shè)計(jì)所需時(shí)間和成本的大量消耗。因此，特殊鋼的研發(fā)方式需要逐漸從傳統(tǒng)試錯(cuò)法向計(jì)算設(shè)計(jì)到實(shí)驗(yàn)驗(yàn)證模式轉(zhuǎn)變�！安牧匣�因組計(jì)劃”自問世以來，在諸多材料體系的設(shè)計(jì)上都發(fā)揮了顯著的作用，但在傳統(tǒng)結(jié)構(gòu)材料尤其是鋼鐵材料上，由于其合金體系的復(fù)雜性、工藝流程的長(zhǎng)鏈條、組織的多樣性以及性能的多目標(biāo)需求，使其成為材料基因工程的難點(diǎn)。但正基于上述特點(diǎn)，傳統(tǒng)結(jié)構(gòu)材料也為材料基因工程提供了發(fā)揮的空間，世界各國(guó)紛紛開展特殊鋼方面的高通量計(jì)算與設(shè)計(jì)。通過對(duì)基于材料基因思想的特殊鋼研發(fā)進(jìn)展的綜述，評(píng)價(jià)了針對(duì)特殊鋼的材料基因工程發(fā)展現(xiàn)狀及未來方向。介紹了美國(guó)西北大學(xué)Olson團(tuán)隊(duì)以及Questek公司通過多尺度集成計(jì)算平臺(tái)研發(fā)的飛機(jī)起落架用超高強(qiáng)不銹鋼、荷蘭代爾夫特大學(xué)通過“基因”設(shè)計(jì)理念結(jié)合高通量遺傳算法設(shè)計(jì)的高性能耐熱鋼、印度CSIR國(guó)家冶金實(shí)驗(yàn)室通過多種本構(gòu)模型結(jié)合人工神經(jīng)網(wǎng)絡(luò)進(jìn)行的高性能管線鋼設(shè)計(jì)等。特殊鋼的高通量計(jì)算與設(shè)計(jì)研究不但可以促進(jìn)特殊鋼的更新?lián)Q代，更會(huì)為我國(guó)乃至世界金屬材料的高速發(fā)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.
