TECHNICAL ABSTRACT:The convergence of new computational capabilities, advanced characterization techniques and the ability to generate and harness large-scale data enables new pathways for the discovery, development and deployment of advanced materials systems. This program engages a multidisciplinary team to develop a fundamental framework for design of a new class of multilayered systems for deployment in new, energy efficient power generation and propulsion systems. Novel complementary computational and experimental tools developed will be integrated with existing tools and applied to a promising new class of intermetallic-strengthened cobalt-base alloys. The unique high-temperature properties of these alloys, when combined with thermal barrier coatings, promise very substantial improvements in powerplant efficiency, motivating GE Energy and GE Global Research as partners in this DMREF-GOALI program. The program will take a systems approach, developing tools and models that permit simultaneous design of the metallic substrate and intermetallic bond coat for compatibility with the ceramic top coat, going beyond the linear, experiment-driven approach historically employed for independent development of these three critical system elements.NON-TECHNICAL ABSTRACT:The convergence of new computational capabilities, advanced characterization techniques and the ability to generate and harness large-scale data enables new pathways for the discovery, development and deployment of advanced materials systems. This program engages an engineering and computer science team to develop a fundamental framework for design of new multilayered materials systems for energy efficient power generation and aircraft propulsion. Novel complementary computational and experimental tools will be developed and integrated with existing tools to accelerate development of a newly discovered cobalt-base substrate material along with compatible environmental protection layers. The program will take a systems approach, developing tools and models that permit simultaneous design of the layered system, going beyond the linear, experiment-driven approach historically employed for independent development of these critical system elements.

技术摘要：新的计算能力、先进的表征技术以及生成和利用大规模数据的能力的融合，为先进材料系统的发现、开发和部署提供了新的途径。 该计划由一个多学科团队组成，旨在为新型多层系统的设计开发一个基本框架，以部署在新的节能发电和推进系统中。 开发的新型互补计算和实验工具将与现有工具集成，并应用于一类有前途的新型金属间化合物强化钴基合金。 这些合金独特的高温性能，与热障涂层结合使用，有望大大提高发电厂的效率，促使GE Energy和GE Global Research成为DMREF-GOALI计划的合作伙伴。 该计划将采取系统方法，开发工具和模型，允许同时设计金属基底和金属间化合物粘结层，以与陶瓷顶涂层兼容，超越历史上用于独立开发这三个关键系统元素的线性实验驱动方法。非技术摘要：新的计算能力的融合，先进的表征技术以及生成和利用大规模数据的能力为发现、开发和部署先进材料系统开辟了新的途径。 该计划聘请了一个工程和计算机科学团队，为设计用于节能发电和飞机推进的新型多层材料系统开发一个基本框架。 将开发新的补充计算和实验工具，并与现有工具集成，以加速新发现的钴基衬底材料的开发，沿着兼容的环境保护层。 该计划将采取系统的方法，开发工具和模型，允许分层系统的同时设计，超越线性，实验驱动的方法，历史上用于这些关键系统元素的独立开发。
