The history of steel dates back to the 17th century. Steel has been instrumental in the betterment of every aspect of our lives ever since, from the pin that holds the paper together to the reinforcement in the construction industry. Path breaking improvements in manufacturing techniques, access to advanced machinery and understanding of factors like heat treatment and corrosion resistance have aided in the advancement of the properties of steel in the last few years. In this thesis, the results of a study aimed at determining the influence of temperature and influence of the quasi static and fatigue behavior of stainless steel 2304 are discussed. The microstructure of the as-received steel was examined as a reference and characterized for the nature and morphology of the grains and the presence of other intrinsic features in the microstructure. The tensile, cyclic fatigue and bending fatigue tests were done on a fully automated closed-loop servo-hydraulic test machine at room temperature. The failed samples of this high strength steel were examined in a scanning electron microscope for understanding the fracture behavior, especially the nature of loading such as quasi static , cyclic fatigue or bending fatigue . The quasi static and cyclic fatigue fracture behavior of the steels examined coupled with various factors contributing to failure are briefly discussed in light of the conjoint and mutually interactive influences of intrinsic microstructural effects, nature of loading, and stress (load)-deformation-microstructural interactions.
