Abstract
P91 martensitic and SS304 austenitic stainless steel is identified as the steels for use in high temperature areas of ultra-super critical boilers. The boiler piping involves similar and dissimilar weld joints of P91 and SS304 grade steels. The welded joints are exposed to high temperature in service and it is therefore required to evaluate the high temperature behaviour of such joints. Hot tensile test is a short-term high temperature test which is a useful tool to study the high temperature behaviour of the welds. In this investigation, shielded metal arc welded (SMAW) similar joints of P91/P91 martensitic steel, SS304/SS304 austenitic steels joined using matching weld metal and dissimilar joints of P91/SS304 welded using Inconel weld metal are subjected to hot tensile test at temperatures of 550 deg C, 600 deg C and 650 deg C. The stress-strain behaviour of the weld joints at elevated temperature was studied.
期刊介绍：
The International Journal of Vehicle Structures and Systems (IJVSS) is a quarterly journal and is published by MechAero Foundation for Technical Research and Education Excellence (MAFTREE), based in Chennai, India. MAFTREE is engaged in promoting the advancement of technical research and education in the field of mechanical, aerospace, automotive and its related branches of engineering, science, and technology. IJVSS disseminates high quality original research and review papers, case studies, technical notes and book reviews. All published papers in this journal will have undergone rigorous peer review. IJVSS was founded in 2009. IJVSS is available in Print (ISSN 0975-3060) and Online (ISSN 0975-3540) versions. The prime focus of the IJVSS is given to the subjects of modelling, analysis, design, simulation, optimization and testing of structures and systems of the following: 1. Automotive vehicle including scooter, auto, car, motor sport and racing vehicles, 2. Truck, trailer and heavy vehicles for road transport, 3. Rail, bus, tram, emerging transit and hybrid vehicle, 4.
