| Abstract | Titanium alloy is one of the most popular materials in engineering applications. Pulsed arc welding can obtain grain refinement of titanium that is a benefit for mechanical properties. However, the study found that the optimized effect decreased with some higher frequencies. Hence, the study of Ti-6Al-4V was carried out with higher-frequency region, and the reason was discussed. The fluid of molten pool had effect on microstructure and mechanical properties of welding joints. Simultaneously, the arc behavior with pulsing current was known as the important factor for the fluid status. Thus, the microstructural morphology, microhardness gradient, and mechanical properties were detected, which were also compared with other frequencies. With high frequency more than 50 kHz, the fluidity of molten pool decreased significantly with low ductility of joints. The mechanism simulation was produced with plane and ellipsoid assumptions, and the results indicated that the conflux caused impact region of double circulation, which was recognized as the main reason for the drops of microstructure and properties with more than 50 kHz. |

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.
