| Abstract | This work summarizes results of the work carried out in CVR (Centrum výzkumu Rez) on the evaluation of the susceptibility to LME (Liquid Metal Ebrittlement) of the ferritic/martensitic steel T91 in contact with LBE (Lead-Bismuth Eutectic) at 300 and 350°C. The work, carried out in the past few years, through tensile and fracture toughness tests, revealed a marked sensitivity to embrittlement for the T91 in contact with LBE. Tests were carried out in well defined conditions and according to ASTM standards. It was observed that the LBE decreased the fracture toughness, JIC, by more than 30%, compared to the value in air. The results are discussed based on examinations of the fracture surface evidencing LME occurrence. The fracture toughness measured in LBE is proposed to be the appropriate value for fracture resistance evaluation, applied to extension of a pre-existing LME crack. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built 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 designed 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 developed, operated and maintained from Indian Institute of Technology Kharagpur.
