There has been a constant search for new materials for high temperature applications, such as for parts of steam generators, parts of thermal power plants, piping of liquid metal reactors, which are likely to be exposed to temperature 5500c and above. Good strength and ductility values possessed by special steels make them the first choice of designers for applications mentioned. Modified 9Cr-1Mo steel has been in use for such applications since a decade. For any given material, along with the mechanical properties, there is a need to determine the creep property if the material is the choice for high temperature service applications. Further, as it has been experienced that the welds are likely zones of failure, under extreme conditions of load and temperature, probing the creep property of the welded joints of a given material becomes an important aspect of research.Hence it is proposed to probe into the creep resistance aspect of the welded joints of 9Cr-1Mo steel under different conditions of load and temperature. It is also proposed to age the samples of 9Cr-1Mo steel under different conditions so that variation of creep properties in both the parent and the weld metal can be studied adopting the indentation creep test methodology. Experiments will be designed to extract all possible information regarding structural disintegration of the material. Additionally, scanning electron microscopy is planned to be adopted to observe micro-structural changes and correlation will be attempted to link them to observed creep behaviour.
