0431271K.L.MurtyDescription：该奖项支持美印合作研究：钛的蠕变各向异性--纹理和微结构起源。印度孟买印度理工学院(IITB)北卡罗来纳州立大学(NCSU)的K.L.Murty教授和Indradev Samajdar教授将研究钛及其合金的各向异性变形行为。化学和热机械加工都会影响这些行为，选定等级的钛合金将在NCSU进行双向蠕变试验。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。通过使用彼此的设施，他们希望在对织构钛合金的基本理解和开发方面取得快速进展，并解决最近关于应用系统中蠕变各向异性的一些观察到的问题。范围：这些研究与预测由这些轻质材料制成的结构在使用中的尺寸变化直接相关，这些轻质材料在航空航天、化学、能源和国防等领域的各种技术中得到应用。NCSU和IITB的专业知识和设施相辅相成。20多年来，美国Pi Murty在锆钛合金领域进行了大量工作，并对晶体织构、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/预测和显微镜方面经验丰富。这项研究有助于将其纳入两所大学的本科生和研究生水平的课程。博士后和研究助理将在各自的家乡和对应机构参与研究。

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.
