开发高相变熵变(ΔS)的弹热材料是弹热制冷技术发展的关键使命。在这里,我们展示了一种自适应设计策略,将机器学习(ML)与理论计算紧密结合,以加速具有高ΔS的多组分Cu-Al基形状记忆合金(SMA)的发现过程。根据线性回归模型,Al、Co、Fe、Ni是Cu-Al基合金中对ΔS有显著促进作用的元素。结果表明,在50万组元的势能空间中,Cu_(72.2)Al_(20.2)Ni_(6.2)Co_(0.7)B_(0.7)具有最高的ΔS值1.88 J/mol K,比文献报道的Cu-Al-Mn三元合金的最高ΔS值分别高9.9%和17.5%。
Exploring elastocaloric materials with high transformation entropy change (ΔS) is a key mission for the development of elastocaloric refrigeration technology. Here, we show an adaptive design strategy, tightly coupled a machine learning (ML) with theoretical calculations to accelerate the discovery process of multi-component Cu-Al-based shape memory alloys (SMAs) with high ΔS. Based on a linear regression model, Al, Co, Fe, Ni are the elements that are beneficial to the significant promotion of ΔS in the Cu-Al-based alloys. In our results, Cu72.2Al20.2Ni6.2Co0.7B0.7is discovered with the highest ΔS of 1.88 J/mol K from a potential space of ~500,000 compositions, which is higher than the highest ones found in ternary Cu-Al-Mn and reported experimental value by 9.9% and 17.5%.
