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.

0431271K.L。 Murtydescription：该奖项支持美国印度合作研究：钛和微观结构的蠕动各向异性。 教授K.L.北卡罗来纳州立大学（NCSU）和印度印度孟买印度理工学院Indradev Samajdar的Murty将研究钛及其合金的各向异性变形行为。 化学和热机械加工都会影响这些行为，并且在NCSU上将对钛合金的选定等级进行双轴蠕变测试。 IITB的微纹理研究以及微结构方面将与这些材料的宏观行为有关。 合作将使研究人员能够在钛合金中六角形封闭式金属和蠕变各向异性的各向异性变形行为领域取得更好的进步。 通过访问彼此的设施，他们期望在质感钛合金的基本理解和开发方面迅速发展，并解决有关应用程序系统中有关蠕变各向异性的最近观察结果。 范围：这些研究对于预测这些轻巧材料制成的结构的维度变化是直接相关的，这些材料在航空航天，化学，能源和防御中使用的各种技术中找到了应用。 NCSU和IITB的专业知识和设施相互补充。 美国皮尔蒂（Us Pi Murty）在锆和钛合金合金中已经广泛工作了二十年，并就晶体学质地，各向异性变形和蠕变进行了学术研究。 印度同行Samajdar在纹理分析/预测和显微镜方面非常有经验。 这项研究使自己融入了两家机构的本科和研究生水平的课程。 博士后和研究助理将在各自的家庭和同行机构中参加研究。
