|Abstract||The development of a series of V--Nb alloys is described. The exploitation of this alloy system allows the design of high-strength, low-density compositions possessing good aqueous corrosion resistance in boiling, oxidizing, or reducing acids and sufficient oxidation resistance to allow their fabrication by conventional hot-working techniques in air. In the warm-worked condition, the spectrum of properties measured under inert atmosphere conditions (strain rate 0.005/sup -1/ sec) includes ultimate tensile strengths of 120,000 to 35,000 psi over the temperature range of 700 to 1000 deg C and stress-rupture properties at 700 deg C corresponding to 100-hr life at stresses in excess of 100,000 psi. Tensile strengths as high as 70,000 psi at 1000 deg C and 40,000 psi at 1200 deg C were observed at higher rates of loading in the warm-worked and stress-relieved conditions. (auth)|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
