高塑性快速实验合金的开发(HT-READ)

High-Throughput Rapid Experimental Alloy Development (HT-READ)

Olivia F. Dippo, Kevin R. Kaufmann, Kenneth S. Vecchio

摘要:

当前的散装材料发现周期从最初的计算预测到制造和分析都存在一些效率低下的问题。材料通常以单一的方式进行评估,主要依赖于人为驱动的成分选择和对生成数据量的分析,因此也减缓了计算模型的验证。为了克服这些限制,我们开发了一种高通量快速实验合金开发(HT-READ)方法,该方法包括一个集成的闭环材料筛选过程,该过程受到广泛的化学分析和现代自动化创新的启发。我们的方法是一个通用的框架,统一的计算识别理想的候选材料,制造的样品库的配置服从多个测试和处理路线,和分析的候选材料在一个高通量的方式。人工智能代理用于找到成分和材料属性之间的联系。新的实验数据可以在后续迭代或新的设计目标中利用。样本库被分配了唯一的标识符并被存储,以使数据和样本持久化,从而防止机构知识的流失。

英文摘要:

The current bulk materials discovery cycle has several inefficiencies from initial computational predictions through fabrication and analyses. Materials are generally evaluated in a singular fashion, relying largely on human-driven compositional choices and analysis of the volumes of generated data, thus also slowing validation of computational models. To overcome these limitations, we developed a high-throughput rapid experimental alloy development (HT-READ) methodology that comprises an integrated, closed-loop material screening process inspired by broad chemical assays and modern innovations in automation. Our method is a general framework unifying computational identification of ideal candidate materials, fabrication of sample libraries in a configuration amenable to multiple tests and processing routes, and analysis of the candidate materials in a high-throughput fashion. An artificial intelligence agent is used to find connections between compositions and material properties. New experimental data can be leveraged in subsequent iterations or new design objectives. The sample libraries are assigned unique identifiers and stored to make data and samples persistent, thus preventing institutional knowledge loss.
