| Abstract | Corrosion tests of martensitic and austenitic steels were performed in a forced liquid eutectic Ph-Bi circulation loop. Experiments were carried out at 470°C and 600°C. Two oxygen concentrations in Pb-Bi were studied: 10-6 wt% and 10-7-10-8 wt%. The results showed that at 470°C, all the tested steels have a satisfying corrosion behaviour for both oxygen contents. An oxide layer is formed on martensitic steels (T91 and EM10); its thickness depends on the oxygen content. It is constituted of an outer layer of magnetite and an inner (Fe, Cr) 3O 4 spinel layer. Austenitic steel 316L is protected by a very thin oxide layer ( < 1 m). At 600°C, martensitic steels (T91 and EM10) undergo an important oxidation for both oxygen contents (after 1000h, the thickness of the oxide layer varies from 10-15 m to 20-25 m depending on the oxygen content). The oxide layer is constituted of (Fe, Cr) 3O 4 spinel and appears porous. Austenitic 316L undergoes severe dissolution at the lowest oxygen content in Ph-Bi and partial dissolution and oxidation at the highest oxygen concentration. Erosion phenomena were observed on all the steels. |

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.
