| Abstract | The goal of improving the efficiency of pulverized coal power plants has been pursued for decades. The need for greater efficiency and reduced environmental impact is pushing utilities to advanced ultra-supercritical conditions, i.e., steam condition up to 710/720 °C and 310 bar of pressure. The long-term creep strength with adequate thermal stability and environmental-resistance requirements imposed by these conditions are clearly beyond the capacity of the currently used ferritic steels and other related alloys. Nickel base alloys, such as IN617 super alloy is one of the preferred choices for steam turbine components used by fossil fuelled power generation plants. In this paper, effect of thermal ageing on creep behaviour of IN 617 nickel base super alloy were studied. Effect of thermal ageing on other mechanical properties such as tensile, yield and impact strength were also studied. Correlation between creep properties and microstructural changes, due to thermal ageing on IN 617 super alloy were also studied. Creep testing was carried out at different stress and temperatures for various thermal ageing conditions (800 and 850 °C) for different time durations and compared. The Alloy (IN 617) shows good thermal stability over long term aged condition with respect to creep strength. Less deterioration is observed in yield strength and tensile properties over long term ageing. |

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.
