| Abstract | The resistance heating is adopted in bulging process of TA15 titanium alloy to improve the heating efficiency and reduce the energy consumption. The experiments of TA15 titanium alloy resistance heating tension and bulging are performed to investigate the influence of current on titanium alloy hot deformation. Compared with conventional hot deformation, the current will lead to strain concentration due to resistance changing when the necking appears. The TA15 titanium alloy resistance heating superplastic bulging can be carried out with a current density of 7 A/mm2 and the current can improve the forming property of material. The results show that the dynamic recrystallization takes place during hot bulging process. In deformation process, a part of α phase transforms into β phase that makes the grains grow up and the β phase changes into the basket weave structure in the subsequent cooling process. Under the action of current, the grain orientation of deformation titanium alloy shows directivity and the dislocation line is approximately in parallel with others with little tangle and screw that can strengthen the ability of the dislocation glide and enhance the deformation ability of TA15 titanium alloy. The resistance heating forming parts are obtained. |

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.
