摘要:

自2011年6月美国提出“材料基因组计划”以来,构建集成的高通量材料计算平台和数据库平台以加快新材料的研发已成为重要的基础性工作。高通量材料计算平台MatCloud提供了一个集成的材料自动流程计算框架,旨在为新材料的设计和计算提供一套通用的方法和技术。二元合金设计涉及到批量结构建模、结构筛选和性质计算问题,为了支持目前在合金设计中应用较广的特殊准随机结构SQS方法,研发了支持基于SQS二元合金设计的高通量自动流程计算相关算法和插件,并在MatCloud平台上进行了实现。该插件支持基于SQS的二元合金结构建模,高通量筛选和性质计算。实现了ZrxTi(1-x)合金弹性模量的自动流程计算,取得了预先设定的效果,提升了计算性能,从而帮助加快二元合金设计。

Abstract:

Since the United States announced the "Materials Genome Initiative" in June of 2011, developing integrated highthroughput computational material platform and computational material database to accelerate the development of new materials has become increasingly important. MatCloud is a highthroughput computational material platform and a software framework for highthroughput material automatic computation, which aims to propose universal methods and techniques for new material designing and computing. Creating a batch of structures, screening structures from vast amount of unknown structures and property calculation are the key problems of designing binary alloy. In order to support the widely used special quasirandom structure (SQS) method for alloy design, we propose a highthroughput automatic calculation algorithm, and develop a "plugin" following the specifications and interfaces provided by MatCloud for highthroughput SQS binary alloy design and automatic computation. The elastic modulus of ZrxTi(1-x)  alloy are then calculated using the proposed method. As a result, all the calculation jobs are computed successfully and automatically, the results are processed without human operations, the preset effects are achieved and the calculation performance is improved. The proposed method and the “plugin” design for constructing binary alloy are proved appropriate and effective, and they can help accelerate the development of binary alloy.
