| Abstract | This study reports the investigation of the fatigue crack growth behavior in 2024 aluminum alloy billets manufactured using the direct chill casting (DCC) and electromagnetic casting (EMC). It was expected that the billets produced from these different casting procedures would vary in terms of their microstructure. Therefore, they should exhibit different fatigue crack growth behavior. The results showed that, the structure of the middle center portion of both billets is not homogeneous and relatively coarse, while the structure of the center and edge portions is homogeneous compared with the structure of the middle center portion. As fatigue crack growth extended through many grains having different morphologies, it became unstable through the overall crack path, and the Paris zone almost disappeared. The effects of 5% rolling and commercially rolled DCC billets on the fatigue crack growth rate were also investigated. Striations were enhanced around Al$_{2}$Cu particles refined by commercial rolling, and fatigue crack growth was stable until large crack length. |

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.
