| Abstract | The paper describes results that were achieved by joining the ferritic stainless steel AISI 430 and the austenitic stainless steel AISI 314 by two-component metal injection molding. Sinterdilatometry was used to compare the sintering response of the materials. To compensate discrepancies in shrinkage during co-sintering, several gas-atomized powder fractions were combined. Using this approach, feedstock combinations which did not exceed a shrinkage mismatch of 5% were processed into micro tensile test specimens by sequential or simultaneous co-injection molding. The ferritic/austenitic interfaces were characterized with a focus on interdiffusion of alloying elements and mechanical properties. Defect-free and well-connected bi-material specimens with magnetic/non-magnetic properties were obtained. Results showed that the interdiffusion between the utilized steels resulted in a local strengthening effect that increased the hardness and mechanical properties of the interface. The tensile strength was comparable to the strength of the base material and all specimens failed outside the interface. It demonstrates that the investigated material combination is suitable to produce magnetic/non-magnetic parts by two-component metal injection molding. |

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.
