0431271K.L. MurtyDescription: This award supports the U.S.-India Cooperative Research: Creep Anisotropy in Titanium - Textural and Microstructural Origin. Professors K.L. Murty, North Carolina State University (NCSU) and Indradev Samajdar, Indian Institute of Technology Bombay (IITB), Mumbai, India will study the anisotropic deformation behavior of titanium and its alloys. Both the chemistry and the thermo mechanical processing can affect these behaviors and selected grades of titanium alloys will be subjected to biaxial creep testing at NCSU. Micro textural studies at the IITB along with micro structural aspects will be related to the macroscopic behaviors of these materials. Working together will enable the researchers to make much better progress in the field of anisotropic deformation behavior of hexagonal close-packed metals and creep anisotropy in titanium alloys. By having access to each other's facilities, they expect to progress rapidly in fundamental understanding and development of textured Titanium alloys and resolve some of the recent observations about creep anisotropy in application's systems. Scope: These investigations are of direct relevance for predicting the dimensional changes in-service of structures made of these lightweight materials that find application in varied technologies used in aerospace, chemistry, energy and defense. The expertise and facilities at NCSU and IITB complement each other. US PI Murty has worked extensively in Zirconium and Titanium alloys for more than two decades and has conducted academic research on crystallographic textures, anisotropic deformation and creep. Indian counterpart Samajdar is highly experienced in texture analysis/prediction and microscopy. This research lends itself to incorporation in courses offered at undergraduate and graduate levels at both institutions. Postdocs and research assistants will participate in the research at their respective home and counterpart institutions.

0431271提供。该奖项支持美国-印度合作研究：钛的蠕变各向异性-结构和微观结构起源。北卡罗莱纳州立大学（NCSU）的K.L. Murty教授和印度孟买理工学院（IITB）的Indradev Samajdar教授将研究钛及其合金的各向异性变形行为。化学和热机械处理都会影响这些行为，选定的钛合金等级将在NCSU进行双轴蠕变测试。IITB的微观织构研究以及微观结构方面将与这些材料的宏观行为有关。共同努力将使研究人员在六方密排金属的各向异性变形行为和钛合金的蠕变各向异性方面取得更好的进展。通过访问彼此的设施，他们希望在对织构钛合金的基本理解和开发方面取得迅速进展，并解决最近在应用系统中关于蠕变各向异性的一些观察结果。研究范围：这些研究与预测这些轻质材料制成的结构在使用中的尺寸变化直接相关，这些结构在航空航天、化学、能源和国防等各种技术中都有应用。北卡州立大学和印度理工学院的专业知识和设施相辅相成。美国PI Murty在锆和钛合金领域广泛工作了二十多年，并在晶体织构，各向异性变形和蠕变方面进行了学术研究。印度的Samajdar在纹理分析/预测和显微镜方面经验丰富。这项研究有助于将其纳入两所大学的本科和研究生课程中。博士后和研究助理将在各自的家乡和对口机构参与研究。
